Items Disappearing from Player's Inventory

"Need"? Good question. Some of them... absolutely. Others, I'm not sure. I've just had them selected for months.
5e v3.3.3
Core v3.3.4

That was a typo... both should be 3.3.4

Not a good overall plan. Extensions override the base ruleset code and can become incompatible with FG ruleset updates - resulting in old/incompatible custom code being ran and causing all sorts of errors or unexpected behavior.

5e v3.3.3
Core v3.3.4

The latest 5E ruleset is v3.3.4. Running an older version of 5E won't help. Do you have an unpacked 5E directory in your <FG app data>\rulesets directory? Or does it look like 5E.pak hasn't been updating as part of a previous update?

I've just done some tests with v3.3.4 and no extensions - using unidentified items from campaigns and modules and I can't recreate the issue you're seeing.

So, what I'd suggest is:
1) Update so that the 5E ruleset is v3.3.4.
2) Disable the extensions you don't really need.
3) Check for compatibility of the extensions you are using.

Yeah... Sorry... That should have said 3.3.4.

Yeah... Sorry... That should have said 3.3.4.

No worries. So we're down to removing unwanted extensions and checking the remaining extensions for compatibility.

The NPC spell slots extension is no longer needed since that is built into the code now.
