destiny 2, Two bugs blocking my progress: gunsmith/vanguard engrams not registering + can only buy weapons via decrypt (stuck at Guardian Rank 3/4)

Hello, I’m also stuck and I’d like to know if anyone has already found a solution.
I’ve only been playing for about a week, and I’m looting quite a lot of stuff, but here’s the problem: whenever I pick up an engram in-game — whether it’s a Gunsmith engram or a Vanguard engram — it never actually gets added. When I go to the vendor tied to that engram (for example the Gunsmith), the counter is stuck at 0, every single time. Only classic/regular engrams seem to register properly; the special ones (Gunsmith, Vanguard, etc.) just don’t.
Because of this, I’m also stuck on Guardian Rank 4, where I’m supposed to buy a weapon directly from a vendor. The problem is that my only way to buy a weapon right now is by decrypting one, and that requires Gunsmith engrams — which I can’t get credited for. So I’m blocked at Guardian Rank 3/4 because of this combo of two bugs:
1. Engrams I loot in activities don’t get added to the vendor count.
2. My only way to buy weapons is through decryption, which depends on the engrams from bug #1.
I saw that some people had a similar issue where the engram/rank rewards only show up after physically revisiting the Tower or the specific vendor — has anyone tried that and confirmed it fixes the counter, or found another workaround? Any help on either bug (or another way to buy/unlock a weapon to progress past Rank 3) would be really appreciated. Thanks!
