[GNC] Last Num Bug(s) ??

[viking2ev at san.rr.com]

I am using GnuCash v5.1


I use the "Num" field in the account register to log the transaction number
(e,g, check number or other reference). 
I want to see the latest transaction number in the  "Account Tree window".
I have therefore set my "Account Tree window" to show the "Last Num"
Heading.


Bug1:
For the last transaction in my Bank1 account I have set the "Num" field to
50.
The "Last Num" Heading in the "Account Tree window" then properly shows 50.
I then edit "Num"  to 51. 
However, the "Last Num" Heading in the "Account Tree window" is not updated.
It still shows 50.

Bug2 (maybe not a bug?):
Instead of using integers in the "Num" field, I would like to use use
decimals; e.g. 4.5.
However, that is not recognized in the "Last Num" Heading in the "Account
Tree window". It still shows the previous integer value for the "Num" field.
