Columns problem

Hi, have a problem with showing columns.
For example in IP - DHCP - Leases
If I click on arrow - Show Columns - check Last Seen, columns are bad. Don't see Last Seen column, it shows me a lot of other columns, some columns are hidden again.

Distribution (please complete the following information):

• Name: Ubuntu
• Version: 20.04 LTS

** snap version **

latest

** snap info winbox **

3.30

btw when will be 3.31 available?

Thank you
