I have this consistent leak in the middle of my frames. I thought that I had at first messed up replacing the seals, but the leaks persisted after I replaced the light trap once more.

There is some damage on the edge of the back, which seems to roughly line up with the position of the leak, but not perfectly. Could this be the cause?
