Hi, I have a problem with ExteriorAlgebra and I do not understand where I am wrong. Let's define an ExteriorAlgebra E with some generators:

E.<e1,e2,e2> = ExteriorAlgebra(SR)

Take for example e1 and compute

e1.interior_product(e1)

which gives 1, correctly. If I instead compute

(e1.interior_product(e1)).constant_coefficient()

this gives 0!

It worked correctly until time ago, this behaviour only appear now: so probably I'm missing something that changed recently. I'm using SageMath version 9.7 on CoCalc.

Thanks in advance!
