Checking the formula E1, then selecting the Num allows for the creation of the new variables.

I still initially get the Error: Syntax Error message, but it goes away once I:

Go into the Num screen, then press ESC, and finally back into the Solver App. E1 showing up as the formula as requested. If i go from Num to Symb i still get the error message.

hmm... that may be a clue. E1 used to autocheckmark itself using the prior firmware. Perhaps since it saw a "valid" formula in E1 but sees an error now.
