PDMWE not showing updated view

I made some changes to a model/drawing and when I look at the file in SW it is fine but viewing it in PDMWE it is still showing as the old version.  I am using SW 2010 SP4.0, and PDMWE 10.4.  This has been an intermittent issue and I can't seem to get a straight answer as to why it happens.  If anyone could help I would appreciate it.

Thanks...
