[v12.10 -> 12.16] Legacy Promotions - Code column missing from UI after upgrade

Hi,

I've just upgraded our Commerce Manager and Commerce Manager Core packages from 12.10 to 12.16 and it seems that the column that would normally house the promotional code in the legacy promotion section, is missing.

Was this an intentional change? I've not seen much about it in the release notes.

Thanks,

James
