Posts disappear when I log in - eviltoast

Upper screenshot is looged in - last post shows up in !3dprinting@lemmy.world as 10 days old. Next one is 6 months old!! Lower screenshot is logged out - there’s a bunch of new posts dating a couple of hours ago.

I picked 3dprinting community just as an example - it happens all the time (sometimes communitys have number of posts displayed but they load as empty)

I changed language in profile settings to “undetermined”, tried some other stuff but nothing seems to do anything. Please help!
