Spam messages for mcMMO party owners

This is an issue many people on my server have been encountering since last week. How do we fix this issue / is there a command for the players to do?

Here is a screenshot of the issue

Some more information - this happens whenever a member of their party mines a block.
Thanks!

On the surface this looks like a plugin conflict, try running just mcMMO and seeing if the issue still happens

What plugin could this be interfering with? We have never had this issue before like a week ago

It isnt happening for everyone, only a few parties, I realize my initial statement was a bit vague
