Cannot add RSS from showRSS.info

[Agnapot]

So, I just downloaded this, very excited to replace the TVShows preference pane from way back, however when I try to add an RSS feed from showrss.info it does not allow me to click "Add Feed". If I modify the URL and delete a letter from the showrss.info part, for example, changing https://showrss.info/show/1156.rss to https://howrss.info/show/1156.rss then the button lights up, however if I add a letter, like https://ashowrss.info/show/1156.rss, it remains unlit. Screen caps are attached.

Thank you for any help!

Ok, so, I resolved this after some googling. Turns out I guess Catch assumes you have an account with showRSS, so it requires some inputs to the URL. If you add this string to the end of the showRSS URL it works:

?magnets=true&namespaces=true&name=null&quality=null&re=null

Such as

https://showrss.info/show/1433.rss?magnets=true&namespaces=true&name=null&quality=null&re=null

So, mystery solved! I guess!
