We noticed a weird behaviour in our grid and we don’t really know what’s causing the issue.
We have two buttons in the statusbar, one applies a filter and the second removes all filters.
After applying the filter the first time everything works correct:

After removing the filter and applying it again, “Please Choose” will be added to the combobox. After that everytime the filter will be applied, “Please Choose” will be added.
