Clips in timeline use incorrect speed and incorrect selection from source
When I load a project that was working properly when I saved it, some of the clips in the sequence have switched which part of the source media they're pulling from. It's always still the correct source media, just the wrong part of it. Some are also bizarrely slow- slower than the % speed I've chosen in Time Remapping or Speed/Duration. I can't seem to find a commonality between the affected clips that differentiates them from the unaffected; many unaffected clips have the same speed effects applied. In addition, when I try to replace the affected clips with new ones pulled directly from the source media, they continue to have issues with not reflecting the % speed I've chosen. The one I mostly recently tried to replace appears to be running full speed instead of 50%. I'm editing off a new hard drive, that's the only recent change in my setup. Some older saves don't have this issue, so I tried rebuilding the project from one of those, just adding some adjustment layers from the new save, but when I opened the rebuilt project this morning, the same issue occurred. I've tried resetting preferences, reinstalling Premiere, deleting the media cache, all with no luck.
