Problem with Chitubox Slicer

[supaman8472]

So I am knew at this and after creating a cube I needed it was to large. So I decided to split it into two pieces and make slots to hold them together with minimum glue. However, after using the Chitubox slicer it seems to have change a few things on the cube. I have added photos so it is much easier to see what I mean. Also, let me know if this is just a software bug and it will not affect the print or if there is something wrong. I have tried re-slicing a few times and it comes out the same.
Thank you all.

can you show/upload the *.stl-files, to check them?

Looks like there's some bad geometry on the part you need to fix.

Also, what you are trying to do is extremely difficult on resin printers. You need to correct for light bleed and shrinkage, both of which are dependent on the geometry, so really requires printing and testing over and over while you tweak.
