Kodi Repeatedly Asks to Confirm Copy

Hi,
On each operation\selection\etc I make on my movies library, Kodi keeps prompting with a pop up:
‘Confirm Copy’ \ Need to unpack a big file. Continue?
and always for the same two .avi movie files I have in my library.
Is there any solution to stop this? using the movies is almost impossible with this message prompting on each key press.
Thanks,
Yotam.
