Audio and Video out of sync after exporting in both Premiere and Rush

Hello,

So I've looked through the forums to see if there is another post about my issue, but I havent found any that really help. I am making videos that at most have 5 clips in them and they are all at 60fps except for the one picture I use. Everything looks perfect when I look at it in the perview screen, but when I export it the video is really slowed down but the audio is fine. I checked the settings when I expot and it says 60 fps as the export. I have used the clips in both Premiere and Rush, and have even installed other versions of Rush to try and fix it (I orginally used the most up to date versions) Am I missing something that  I can change? I just don't know what to do to fix this issue.
