It's just another problem of HFS 2.4 default template, and the direct fix is stated in a GitHub issue/forum report. (see below)
Also, switching to another template (with working "delete" function) can help.
Choices are Takeback and Mobil-light. You can find them in
Template sub-board 
I think @NaitLee or @Danny already reported a similar this error (I can't remember).
... I think it's
dj found this bug first

The GitHub issue:
https://github.com/rejetto/hfs2/issues/10There is
maybe one/some report(s) in
Beta sub-board too

(ps. see dj's post here. this post is a bit later than that, but started editing before that)
Also, rejetto... For this whole year, the only time he speaks here is to celebrate my

Now the cake is in his profile now...

🎶 Happy birthday to you 🎵, rejetto
