Deleting recordings in UI leaves some in the folders

I tried to do a search for this subject but I couldn't seem to find one that fit my scenario exactly.

I was deleting some old recordings today and noticed that even though they disappear from the UI and seem to be gone, if I go to the actual folder, some of them are still there. It seems like some of them do get deleted, but not all of them.

I am running the DVR on Windows 10 and am staying updated as you release the Beta DVR (just updated this morning in fact).

The files are deleted an hour or two after you hit delete. You will see messages in the Log when the files are deleted.

Ok, thanks. That makes sense now that some are gone by the time I check it out.
