Files are no longer with certain tasks, help please??

For some strange reason, files that I could find under a tag I can no longer find under that specific tag. These are about 3 tags which when I click are missing all files.

However, I did some digging and found the tags folder and in there are all my files under the relevant tags. So they are still on my computer but I can no loner access them from the Punakea program.

Please help as I need to get this fixed asap. Thank you very much.
