Custom filter model causes error when inside a column group

[Emily-ejag]

Describe the bug

When the ColumnGroup type attribute is set on the columngroup, it is possible to filter using displayFilter: row. However, we need to use displayFilter: menu as our filters are slightly more complex. This is currently not working as of PrimeVue v4.2.4
