Deltamod doesn't delete broken mods when instructed to

[probablyjassin]

I opened Deltamod after the most recent update, and my only previously installed mod was now flagged as broken:

Some mods failed to load
Some mods didn't load correctly. Here are the details:
Mod ID 'Mod_02cf688640fdc8dc8e6e8e245736c4ad'
warning
Failed to read meta.json.

When asked whether I want to delete the faulty mod and I press yes, it does not delete the mod.
