Errors appearing when enabling debug mode

Hi there
I was disabling the debug mode and ended up finding a heap of errors that seemed to be coming from the plugin.

I have posted the code errors which appear to be posting two per button that I created.

Has this been raised as it would be great to get it sorted.

Cheers and thanks in advance.
