sage - Trying to understand why a newline character was added to simplified Finitely Presented Group

I was working with some large Finitely Presented Groups in sage and encountered some unexpected behavior. For one particular group, a newline character is introduced to the string representation of the finitely presented group after calling the simplified() function. I tried looking into the source code for the simplified function, but I am rather new to sage and GAP and nothing presented itself as an obvious source of this behavior.

I am running SageMath version 10.4 with Python 3.11.2.

It may also be worth noting that I have generated thousands of groups of this same type, many of which have been this size or larger, and never encountered this behavior before.

This is the group that produced the newline character:

G = FreeGroup(208)
L = [G([1])*G([12])**(-1), G([12])*G([204])**(-1), G([204])*G([1])**(-1), G([1])*G([11]), G([11])*G([202]), G([202])*G([1])**(-1), G([2])*G([9])**(-1), G([9])*G([127])**(-1), G([127])*G([2])**(-1),

F = G/L
K = F.simplified() # has a newline in it and I don't know why
K.simplified() # still works, so somehow despite the newline character the group behaves well in GAP

Displaying F produces the expected output:
