Corner doesn't appear

Hello again.
I hope you don’t mind keep using the forum to clear these simple doubts.
Sometimes when I place a corner it doesn’t appear on the glyph unless I add an extra node.
Why? Is it a bug?
Thanks for helping.

What version do you have? That should work.

Version 2.4.4

Can you see if the problem is solved in the latest cutting edge version?

Where can I download it?
It doesn’t show up on the updates.

Sorry I had the cutting edge box unchecked.

Ok I’got the cutting edge version but the same problem situation happens.
What should I do?

Can you send me the font to support at this domain?
