Is it possible to search on Service Groups in FSM beyond level A?

We have our service regions in Org Service Group B in Place as shown below.

However when you put the Org Service Group B field on the search pane on the Place screen and try to use it the dropdown displays a small black vertical line only as shown below.

It should display the active Grp Level B values form the code table below.

What I did notice is tha if you place Org Service Group A on the search, the dropdown displays all active code values regardless of group level. So I can select “Scotland” for example, which is a Group B level however the search returns no results given the application is searching Org Service Group A for a value that is held in Org Service Group B

So it would appear that searching for anything other than level A is not supported - unless there is a workaround.

I hope that makes sense.

Thanks,

Barry
