TOPIC: Bug in Back End?

System info: Joomla 2.5.8; DTRegister: 2.8.4

Problem:
- I include three user-defined fields in my registration process. Two are radio buttons. One is conditional, and if selected, causes the third field to appear (a text box). The registrant enters a voucher code in that box if they are using a voucher.
- In the back end Registration Records Manager: When I want to view the information for a group registration, I click on the link in the Members column. This brings up a floating box that includes a display of the information regarding the registrants, including column headers for the three user-defined fields
- Randomly, those fields are sometimes empty (even though clicking on an individual's details show the information they entered), one column will contain information, but not the other two, or two fields will contain information, but not the other one.
- Randomly, the pop-up box will disappear immediately after displaying. At those times, I am not touching the mouse or keyboard.

Fixes needed:
- Always display the data entered in the user defined fields in the group pop-up box
- Permanent display of the box until intentionally closed by the user.
