Bug in solve app?

[DrD]

In the Solver App, does the result shown for B happen to be −6.80ᴇ−4 as the displayed value? Your ellipsis cuts off any possibility of the power of 10 in the result.

In matrix form, if

M0:=[[−15.5,−50.5,−5.5],[−39.5,−4.5,−14.1]]

And

M1:=RREF(M0);

Then
M1(2,3) == B == −6.80ᴇ−4 == the result shown in Solver App
