I asked NukeDPL on my Miraheze wiki to delete a bunch of images, 300+ and it ended up only half-deleting the files.

I used the "titlematch" param to delete the files, as all of them shared the same first part in their name.

Exactly, I typed out "titlematch = animalspecies%"

Here is the bugged result of the mass deletion:

As you can see in the image, the file I asked Nuke to delete still exists, but I am unable to delete the file at all.
The only way I've found to properly delete the file is to click the "Undelete" button and go through that, and then manually delete the file using the "Delete" button under Page Tools.

In the image, I am on the "Unused Files" special page. The second image is one that I manually deleted like how I explained above. The rest of the images after it are still "bugged".
Here is one of the image's deletion logs if that is needed:

NukeDPL did not throw up any warnings or erros when asked to mass delete the files in this way.
