[GNC] Additional 'Accounts' columns not being saved on closing program

[G R Hewitt]

Gnucash 5.4
MacOs High Sierra 10.13.6

Hello,

I have been unable to find a reason as to why, in the 'Accounts' tab,
the additional column 'Total (Period)', in this case - or any other I
choose -
will not save when I close GnuCash, meaning I have to re-select them for
each session.

Whilst this is not the end of the world - obviously, it is annoying and any
help
in solving it would be appreciated.

Thanks in advance.
