Looks like voxelmap is a litemod extension. I read online that litemods are designed not to affect forge mods. Not sure if that’s true or not but it might not change anything.
What I suggest is test with Journeymap rather than voxelmap, if that doesn’t fix it you are going to have to try removing everything other than Aether and adding them all back in one by one. I would suggest trying Aether and Gregtech first so as to confirm that’s not the issue.
EDIT -
Also your Gregtech is severely out of date, you should be on 6.14 by now, of the other mods you have I use fast craft, inventory tweaks and twilight forest, they are all up to date on your end.
