Trail Ruins suspicious gravel/sand don't drop loot on XBox

Somewhere in the past hour while playing, my Realm updated from 1.20.50.3 to 1.20.51.1, and somewhere around this time I found a completely submerged trail ruin. Unfortunately, none of the suspicious sand/gravel blocks drop any loot, though they behave normally other than being "empty". When I checked my Realm backups several minutes into experimenting with the sus blocks, I could see the version update, which is the only reason I know it updated while I was playing. By the time I got back to the trail ruin after reverting to a backup from just before the update, the Realm had updated again, and the problem remains (which is a real shame, because this trail ruin is uncommonly lovely, and appears to have generated intact).
