Default sigma() appears to be broken

Code:
05/26/21 10:01:49 v1.35-beta @ math97, System/Build Info: 
Using GMP-ECM 7.0.5-dev, Powered by GMP 6.2.0
detected         Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz
detected L1 = 32768 bytes, L2 = 8388608 bytes, CL = 64 bytes
measured cpu frequency ~= 3392.250200
using 1 random witnesses for Rabin-Miller PRP checks

cached 664579 primes. pmax = 9999991
 

>> sigma(28,1)
