[Wien] cell parameters are not consistent

Hi all,

I am setting up files using StructGen of C2/c symmetry crystal with 4 inequivalent atoms as below

C 2/c

a 7.247 b 11.697 c 5.090 alpha 90 beta 134.226 gamma 90

Positions
283    0.0   0.134 0.75
23   0.0 0.370 0.25
8   0.261 0.051 0.380
8   0.354 0.208 0.861

It's a monoclinic structure with 4 symmetry elements, group 15 from Bilbao server. StructGen, however shows B2b as group 15, I assumed it's due to the unique axis b so I still went with it. But then I am getting 'Error - cell parameters are not consistent with space group' no matter what. By looking at the struct file, it's clear that something is not right since there are no symmetry operations. I got structure from some other computational paper so positions should be right

Thanks

Jonas
