I encounter this error with select files. These files even if re-encoded yield the same error. The error appears once when they are set to be edited and multiple times when a fragment is saved. At the end of the series of errors, it says that there is no overlap between the pins and cancels the process. Many features of windows explorer get unresponsive when these errors are displayed like drag and drop functions.
All these files have external SRT subtitles. They only give error when they are picked up from the folder. Without they work fine.
