I cant find any other topics about this and it wont let me create a new one but 

It is conflicting DynamicCupShare from incase others getting same issue paid plugin

Had to downgrade vanish update to work with it

Its from the chaos site as I know alot of servers use it to just let everyone know incase they getting same conflict issue.

They are conflicting because they are using different values. DynamicCupShare needs to switch from returning true to null to avoid this conflict warning.

This is from developer of that plugin

The hook cant change in this plugin. If it does then you will lose dynamic sharing of all locked entities. Since this plugin has been this way for almost 3 years and it is Vanish that was recently updated I suggest you go tell the developer to fix it on their end

Merged post

seems to be all good now though in latest update
