Won’t delete WordFence (?) files

Thanks for Plugins Garbage Collectors! I downloaded it onto four sites and it worked perfectly on three of them, cleanly removing dozens of leftover files from the past few years.

But it failed to remove what appears to be old WordFence files from one site. Here is a list of those files:

wp_djgv_wfbadleechers 0 1 Unknown deleted?
wp_djgv_wfblockediplog 0 1 Unknown deleted?
wp_djgv_wfblocks 0 1 Unknown deleted?
wp_djgv_wfblocksadv 0 1 Unknown deleted?

wp_djgv_wfthrottlelog 0 1 Unknown deleted?

Any advice on how to get rid of these?

Thanks in advance,
