Solve app bug report

[roadrunner]

The solve app does strainge things when there are more than 12 variables.

This is on the emulator, 2.1.14592
Windows 10 version 1909

Here is an example:

Reset the Solve App, then tap Start;

Press escape, then go to the home environment;

Copy and paste each of the 6 lines below into the home command line, press enter after each line:
'A=B+C+D'▶E1;
'B=C+D+E'▶E2;
'C=D+E+F'▶E3;
'D=E+F+G+H+I+J+K+L+M'▶E4;
0▶A▶B▶C▶D▶I▶J▶K▶L▶M;
1▶E▶F▶G▶H;

Go to Symbolic view and check E1 thru E4;

Go to Number view, check A thru D, uncheck E thru M (M is located on the second page)

Tap Solve.

M mysteriously checks itself and is solved for. Go back to page one and A is mysteriously unchecked.

Check A, uncheck M, tap solve; and it repeats.

The Solve app when equations have more than 12 variables does other weird things as well. See this thread for another example:
