Last option you can pull the clips in and out using Trim and make sure you make sure the dissolve rests on a new different frame on the timeline. the visual effect is not "identical" but I don't think it would be a deal breaker if my first suggestion doesn't work for you. If this doesn't work you could try changing the default transition from cross dissolve to film dissolve. This in essence resets all the preview files PPro has generated (which I believe is where the problem is). Then add black video or a color matte (black) which is the length of your program to the bottom (first) video track. The fix move all of your video (select all) up one layer.

You didn't mention which version of PPro you are using but in version CS6 and prior there IS a bug with cross dissolve which is a bit idiosyncratic.
