Bootstrap Modal Bug

So I created a report, then wanted to add/remove some keywords but when I tried to do so the plugin (in dashboard) error’d out on modal load.

I then went to my account on knowmyrankings.com and tried to add/remove keywords but it asked me to upgrade even though I removed keywords first.

I then deleted the whole report, and am now trying to create a new one with no luck (again due to modal bug).
