I have not seen that issue, but to confirm, if you are in the form editor and SHIFT-click on the column you will get properties for that column. 3 things to check, 1). What is the label width? It defaults to 90, but for testing make it larger, like 200. 2). There is an option to display label to LEFT. make sure that is check, and 3). Forget the wording but something like display size as defined or all available space and change it to defined.
Let me know if this fixes it.
