I've discovered a problem when upgrading the walls of my town in Minecolonies. The decoration block acts as if the wall was turned sideways upon an upgrade. I'm wondering if anyone is familiar with the decorations code upon an upgrade, maybe there was an error somewhere in there.

Always, thanks for any help with this!

Edit:
Currently running Minecolonies Version 1.15.2

nvm, if u find this bug issue make sure u are running the newest version of minecolonies, it worked for me!
