When using both column (quick) and advanced filters on the same page, the behaviour seems surprising.

(Examples relate to default demo at https://www.phpgrid.org/demo-center/ )

• When I set the first column filter (Product Name := ‘co’), the grid writes the same condition to the advanced filter (Product Name contains ‘co’).
• Any further changes of column filter have no influence on advanced filter. If I set Product Name := ‘s’, the advanced filter still remains: Product Name contains ‘co’
• This first setting cannot be erased from advanced filter by clicking Reset. Any other manually added setting can be erased by Reset.
• When using column or advanced filters, always the last one is valid, never a combination of both of them.
• Both the filter settings remain visible, even though they are actually not used.

As to me, the expected behaviour is like this:

• both the filters are set independently
• filters work together; I mean combination of column AND advanced filter is applied to query
