Upgraded homebrew dagger will no longer become attuned when box is clicked

Hi all,

I have recently taken a previous homebrew dagger, and upgraded it.  The original was able to be attuned without any issues, however now I cannot make the new dagger attunable. 

Original:

Upgraded:

https://www.dndbeyond.com/magic-items/2076937-keen-jagged-dagger-of-the-raven-queen-3

The biggest difference is that the second dagger is now a plus three, and the word "Keen" is added to the description and title.

Any thoughts?

Thanks!

Hmmph.  It figures.

Within 10 minutes of posting my original message, suddenly things started working.  

I am still confused. 

Cheers!

It can sometimes take up to 20 minutes for changes to homebrews to filter through to the character sheets.

I am guessing that is what happened, thanks!
