Hello techconnect,
Here's my answer. Adding one more column to your screen will fix the issue. Right now you have three colums on your screen and out of which left two columns are occupied by other text object and on the third column when you add a textbox or any other object, they do not expand properly because of the limited space. I have tested this on my account and by adding one more column fix this issue.
You can also narrow down the space beween the text box caption(TVCReligAffil) and the box by renaming it to "  TVCReligAffil". This moved "TVCReligFill" to start 7 spaces over to right. You can rename it with as many spaces as you want to fit it to your requirement. In this case it is   + 7 spaces + TVCReligAffil.
Hope that helps!
