Empty rows created after sorting FMXGrids?

Since long time I have the issue with filtering and sorting.
When sorting few times -> empty rows are generated automatically!?

How to reproduce:
just use the TMS demo application "FilteringDemo"
- add in the grid property - Options - Sorting - Mode -> gsmNormal
- run the application
- enter a character in the filter edit box (e.g. "a")
- remove the charater in the filter edit box
- sort the column "Brand name" few times (asc, desc) by clicking on the column header
-> empty rows are created - more and more!!!

Anyone have similar issue?
