Error in formula reference rollup result

There are two Notion Databases:Project and Task.

If no errors, When I change the status of one task to "Done", The one of Project's Show_Done column will show "Done: 1".

But now it doesn't worked and will show the wrong number.

This is the website.

not empty(prop("Status") == "Done")

2.In Project Database - "Num_Done" column - [Rollup]:
Relation: Task
Propety: Done
Calculate: Checked

3.In Task Database - "Show_Done" column - [Formula]:

"Done:" + toNumber(prop("Num_Done"))

Thank you for extending, I just did some tests and it is a Notion bug, so there is nothing you can do to fix.

I already reported it and you should do it as well contacting Notion support using the question mark at the bottom right.

For sure this will be fixed quick.
