Hi Divia,
I'm glad to hear that you found a solution for the original question. This new issue certainly looks interesting.
You can try to change the captions using the Caption Editor (Application-wide Settings) back to their original settings. You may need to find the caption keys being used through the dataelementconfiguration XML. Then, search for each field caption using the key in Caption Editor and you'll be able to change them back. If the keys don't exist in Caption Editor, I guess they will have to be recreated and the text reassigned to them.
Kind regards
Matthew
