Configured timezone working with date last active but not with a custom field (date/time)

Your software
My Mautic version is: 3.2.1

Your problem
My problem is: I have added a custom field signup_date on my mautic installation and it is of type date/time.
I configured that field to show as a column.
now both the entries date last active and signup_date (my custom field) are saved as utc but in the columns date last active is shown according to current timezone and my custom made field is showing in utc only
^ in columns
^ in a particular contact’s details
