I don't know for sure this addresses your problem,but it might.
You might want to just start over with the whole installation.
Bases to receiver-- Are the bases accurately cut to to match the receiver?
You may not believe it,but I have seen bases that were horribly mis contoured.
We take for granted we can just screw on scope bases,good to go. Thats not always true. Most folks don't have the tools,but I set up the receiver on a surface plate and run a dial indicator over the bases front to back and side to side. After all,its MY rifle I'm setting up. From the rear base through the front base,I want it flat within .001. If its not,I use a fixture to hold the base vertical by the surfaces the ring clamps to, I preset a boring head to match the receiver radius and I remachine the bases.
That done,I make sure the screw threads are bottom tapped and the screw lengths are correct.
That done,I put a drop of sleeve and bearing mount Loctite between the base and receiver and some blue paste/stick type loctite on the screw threads.
I screw the bases on,then recheck with the indicator everything is within .001 before the Loctite sets up.
After a few hours, Having already marked the ring cap orientation,I inspect the mating precision surfaces,then install the ring lower halves to the mounts
I tighten them securely,then I give them a few strokes with my ring lapping bar. As the rings are usually blued inside, I can quickly see if the lower ring saddles are true,or need more lapping.That done,I'll put the ring upper halves on to see if they need work. They seldom need much.
All that done,I can set eye relief and level the reticle, Last,I focus the ocular on the reticle while looking at the sky (infinity)
Note,before I install a barrel,I square the front face of the receiver ring. This helps the barrel point in the right direction.
I generally don't have any scope problems since I adopted this process.
I'm also not flexing the tube of an over $1000 scope built to internal tolerances that may be less than .001 as I tighten my rings and mounts.
OK. Not everyone can do all that.
But you can check back over the base to receiver install, Lay a straight edge on the bases. Look for light gaps.
Fit the lower halves of the rings onto the bases and secure them. Then lay the scope in the saddles. Does it seem the rings are aligned? If not,you may need a lapping bar. If its OK,install your ring caps. Once you have level and eye relief,tighten slowly for even gaps at the split,
If the rings are tight on the scope before you mate and tighten then to the bases,they may not mate properly. that can cause your problem.
I just took a close look at your photo. Take your calipers and measure the front and rear receiver ring diameters. Are they the same? (They may not be) IF they are the same, your front and rear bases should be the same height. In your photo,the rear one looks taller. That may be the problem.
Verify you have the right part numbers,
