Adding and removing source fields under program rules

Dear all,

I am not sure if we have experienced this as well with the program rules section for DHIS2 2.26. There is a lock as you name an element to be added to the list of source fields. In-case you need to keep adding new source fields you have to click update for the whole rule to close and revert back to editing the same rule. This makes the process of adding source fields lengthy. This was not the case with DHIS2 2.25. Is there a way this can be sorted out?
