Calibre-web - ebook-convert doesnt seem to be working

The option to load ebook-convert doesnt seem to be working. It was working where it would load it to /usr/bin/ebook-convert but it stopped working and when I go to /usr/bin I cant see ebook-convert. I have the DOCKER_MODS set to linuxserver/calibre-web:calibre. Has something changed? Thanks.

Issue resolved. For some reason there was at the front of the DOCKER_MOD environment variable. Removed it and issue fixed.
