Location Map Module - Clears Advanced Parameters

Good day to you!
I am using the Luxuria Quickstart - hub

When I create a location map module and try to add a module class suffix it clears it upon saving. So I wrote an alternative layout but when I select it in the module's advanced parameters is just goes back to the default as soon as I try to save it..

Yes! It works like a charm. Thank you for the quick fix!
