Android artifact bug

Android 12

The problem happened recently, I got a treasure chest while fishing in the mountain. Inside it had an artifact, I slept in the game and the other day I took it to the museum, it was the last artifact that was missing to complete. Two more days went by in the game and no letters when I checked the artifacts what I got was not registered and still had the question marks "???". The application is in version 1.5.6.37
I didn't use any mods.
I'll put the prints. I used the translator, sorry for any errors in the text.

It's a known bug that sometimes items that you find through fishing don't register on the collections tab.

The collections tab is unrelated to the museum. You are probably missing something else. How many empty spaces does your museum have? It should be 7 spaces. You can compare to the picture on the wiki, or upload your save to the Stardew check up to find out what you're still missing.
