Deleted files still show on List

I installed Serviio to get around an issue I was having with apparently WMP. I would delete files but they wouldn't delete from my file list on the TV
I installed serviio set it, up added a folder, and put some videos in it.
I went to my TV and watched them. I then went back to my PC and deleted the files.
all good except they still show up on my list when I connect on the TV.
The files are GONE from my PC, how do I get rid of them off the TV list? # hours later they are still there. TVs been off two or 3 times. PC rebooted.
Most annoying to have to scroll through a bunch of non existent files to find the one I want.
