I dug a little deeper and it looks like another project with the name “T4T” was added to DBL and Paratext removes duplicate DBL entries (all of them) to keep from having issues if users attempt to install both resources at the same time. This seems like it’s probably a Paratext problem.
(looks like there are 44 resources that are getting hidden from this.)
If you haven’t already, could you create a problem report for this issue?
