Is This Plugin PHP7 Compatible

I’m running the PHP Compatibility Checker plugin to see if there are any plugins that might not be compatible with PHP7 before I upgrade my client’s site now that their hosting has PHP7 available. After running the checker there were warnings about this plugin, so I wanted to check with you to see if this is a false positive, or if maybe the warnings popped up because the version I’m running needs to be updated.

Here are the results:

If it is a false positive, or just because I need to update the plugin, is the current version compatible with PHP7?
