Command blocks resetting when trying to edit them (Realms Bedrock)

Serious Issue on Bedrock Realms.

Attempting to edit a command block appears to reset it. A video depicting the issue is attached.

Placing NEW command blocks and then editing their contents resets them. Existing command blocks do not appear get erased.

Tried it on:

Different locations on my world

Two different devices

An older backup copy of the world on my realm
