Combo Displays vertically stretched

I have placed a combo template in my grid.. It works great until I change the rowheight to accommodate an image within the grid. Once I change the row height the combo stretches vertically and does not display the values unless I click on it. Any advice would be greatly appreciated

Fixed in AW 2.5.5 -
