Was the exporting error "Clip Duration is Longer than Source" ever solved? I do not see a solve, just people talking about it, but no final answer given

When exporting a multitrack as an OMF file, it cancels out after a while and says “Clip duration is longer than source.” I see several past conversations but no final solve or answer. People in the past said they thought it was stretched clips, but it seems it wasn’t. 

Does anyone know how to fix this or what’s really causing it? It’s preventing me from exporting to an OMF file. Any insight would be helpful. Thank you so much!
