Accordion Push/Pull sometimes not working

I have created an accordion menu, and followed the steps on the AxureTraining to do this. When I preview/test it out, however, and open an item, it will sometimes fail to push the rest of the items down, or fail to pull them back up when I close them. Usually if I keep opening/closing the item it will eventually start working again, but I can’t seem to figure out how to stop this from happening. Can someone help me figure out why this is happening and how to fix it? Thanks

I’m a beginner myself and i too had this issue. Till today i couldn’t figure it out why this happens. Maybe it’s a bug in Axure 9? If i remember correctly in Axure 8 I didn’t have this issue.
