Hi, and welcome.
Please take a look at this thread and see if it helps. Since you are on ZorinOS Lite, it may be a bit different but at the very least it's worth checking if this happens when only programs in the snap package format are available.
There's another software manager called Synaptic that is being proposed that does a better job at handling different packages. Perhaps not as visually appealing but it's worth a try.
EDIT: Try the solutions proposed in link above first. I think they look pretty similar but this example may be specific to ZorinOS Core.
As for your other issue with the torrent client, that seems unrelated to this one. Please open a new thread to get help with that, and remember to give as much detail about the problem i.e., when/how it happens, what has changed since it last work, provide logs or screenshots, etc.
