Avast WebRep Plugin for firefox bug found

I have found a bug with avast webrep plugin for firefox. I went to a site like forum.avast.com that i have already voted on, then i reclicked on the Selected rating from before… Then the old selected rating disappeared from there so i couldn’t choose it again but then I clicked on the next one which was on the (Light green) rating option and then the old rating one reappeared but it was selected along with the 2nd selected… I have made a Video on how to perform this glitch to show you about it… I don’t think avast webrep is suppose to do this I’m guessing? I have told avast team member Tech about this a few minutes ago via message… I thought it would be wise to post a topic on this so avast could possibly fix this bug with WebRep in later version? Am I the only one that sees this bug with webrep for firefox?
