Column Styles does not work

My column style settings do not work after upgrading to version 6.1.6.
I had only color-changing settings of the columns.
Has there been a change?

Do you mean you get an error, or simply nothing is affected from the defaults?

after upgrading to version 6.1.6.

Which version did you upgrade from?

I had only color-changing settings of the columns.

Can you give us more details - what specific settings did you use?

Tell us enough to understand and potentially reproduce the problem, and we’re
far more likely to be able to help.
