Museum donations disappearing after reloading on Android

As the title says. Whenever I make a donation, it disappears when I close the app. The slots on the tables free up and I can redonate the same items again. I saw there was a similar thread a couple weeks ago, but they found the cause was DGA, which I don't have installed.

Here's my SMAPI log:
