beascout "Alternate Unit Description" not displaying

[Treflienne 270]

I have tried to set my unit's beascout pin to show an "Alternate Unit Description" by doing the following

1) filling in the text box labelled "Alternate Unit Description" with the desired description, and

2) under "Fields Displayed On Unit Pin", ticking the tickbox labelled "Alternate Unit Description"

Yet my alternate unit description is not showing up, even though all my other changes to the pin are showing up.  (I have observed an overnight delay in any changes appearing on the beascout website.)

Anyone know how to fix this?   Or even who to ask for help?  

Why do I want to change the unit description?  Because the council added a prefix number to our troop number,  and I want the unit description, that prospective families see, not to display the confusing prefix number.
