With a currency column format like this
{ title: "Value £", align: "center", dataIndx: "value", dataType: "float", editable: false, hidden: false, format: "£#.00", filter: { crules: [{condition: 'between'}]} }
If you enter 0 in the left filter box (so any values greater than £0 are listed) a grid refresh causes the left filter box to appear empty although the 0 is still being applied.
I have confirmed this on your own demo
https://paramquery.com/pro/demos/filter_header after adding currency format in your freight column and changing filter to 'in between'.
If another value, like 1, is entered into the left filter box, the filter box correctly displays £1.00 even after a refresh. Also if 0 is entered into the right-side filter box the entry is correctly displayed as £0.00 and does not disappear following a refresh.
The above problem also occurs for the filter type 'greater than'.
Do you have a workaround until this bug is fixed?
