No, it's a new issue as I have the same problem with a bunch of ammo. I went to repackage a bunch of loose 20-round clips in the cockpit of one of my ships (as they are shown in inventory and in the room travel screens) but they don't appear in the equipment screen when I click that tab.

I'd guess that it has something to do with ammo not being required for shooting at least for now. Though I'd say it is odd. Has anyone checked the bug base for a similar issue and posted a new one if not? Likely the best result for resolving it one way or another.
Funnily, someone questioned this in the help room, and Sin had no idea what they were talking about. So presumably no-one made a bug report? Anyway, now that Sin hopefully is aware of the issue, maybe he will take a look at it.
