I mistakenly entered a value in my Max HP Override and now I can't clear that out or reset it.  Is there a way to do that?

You have to delete the contents of that field, don’t try setting it to “0” or anything.

Thanks!  I had tried everything, but didn't think of the delete button!

how do i delete the contents i am so confused help lol

Deleting it and hitting apply does nothing.

This bug is still persisting. Any fix?

taking a long rest did the trick for me!

Clock the field and enter --

I know it's dumb, but Dndbeyond is gonna DnDbeyond.

You don't need to enter --.  Typing anything that's not a number would do the same, but you can also just delete the number.

This actually does not work if you're doing this in the character builder via the little "Manage HP" button that appears on the Class tab. Entering a non-numerical value, or nothing, just causes it to reset to 1 when you click "Apply".

Clearing the field out does work if you're doing it on the character sheet via the "HP Management" sidebar that comes up when you click on the HP numbers.
