Yes and no. According to Adobe it is an as-of-yet unresolved glitch that can happen when bringing Pluraleyes-synced sequences into Premiere. Google “pan to nan Adobe Premiere” to see some other forum posts about it. Resetting “pan” will not work, you have to get rid of any media synced with Pluraleyes.
If you want to salvage your project, the best bet is to export an .xml from the corrupted project and open it in a new project. When you bring in your media, make sure you don’t use anything that went through Pluraleyes. Depending on the complexity of your project this may mean re-syncing a lot of clips by hand. I expedited this process by referencing the timecodes from the corrupted sequence(s). If you’re having trouble call Adobe and they should be able to walk you through it.
