Saving tags with presets not working properly

CorOS Version: 3.1.0

Describe your issue:
On Neural DSP Technologies - Algorithmically Perfect saving tags with presets not working properly. Tags with spaces no longer saved.

Steps to reproduce your issue:
Save a few times, no dice.
Remove spaces, saves OK

I expected this to happen:
Save spaces between words inside tag

I have tried the following things:
Tried clearing browser cache, restarted browser. This worked fine a few days ago.

Can confirm this. “Deluxe reverb” doesn’t work, but “deluxe” or “reverb” by itself is acceptable. Error message looks like this:

Interestingly I don’t get that error, it just fails to save it.
