Combo filter in header displays the KEY instead of the VALUE

I have a grid with combo filters in the columns. Each combo filter represents (key,value) pair with available options to choose from.

In the grid cell when u select from the combo it display the chips with the VALUE but in the header the chips are displayed with the IDs instead. This happens when you select some element from the combo dropdown list!

This happens when u try to interact with the filter combo BEFORE u have clicked on some of the cells in the column. If u once click on a cell and display the dropdown menu then the header filter behaves as expected.

THIS DHTMLX PRODUCT IS REALLYYYYYYYYYYYYYYYY BUGGY!!!

Is somebody reading this forum? I have submited this BUG almost TWO WEEKS AGO!!!

Since v. 7.2.5 u are trying to make it work. Put the vodka away and finally fix this (key, value) dropdown.
