libgap seems broken

I noticed that GO(4,4,1) is returning order a group of order 72 while native gap returns 7200. Apparently it doesn't encode the order of the field correctly and always sets it to 2. Run the following to verify the error

sage:libgap(GO(4,4,1))

GO(+1,4,2)

or

sage:libgap(GO(4,GF(4),1))

GO(+1,4,2)

This is in 'SageMath version 8.1, Release Date: 2017-12-07' on ubuntu 18.04 apt installation.

Is there some other way to access native GAP commands in a worksheet that I'm overlooking?

In particular I'm just interested in evaluating the native gap command

Order(GO(1,4,4));

Like that

sage: %gap Order(GO(1,4,4));
7200
