(yeah i know... should be in square pixel. But they are old clips and and were working fine in R5)
Well all those clips with non square ratio pixel, they don't play. Click them, dont play.
their width show up as 0

But what is weird, if i drag and drop the video clip from the explorer and replace the video track in the clip tab. It will be replaced and will work.... For that session. Next time i open that composition , won't work again (even i save the composition )
if you wanna try it with one of the clip having issues:
