been playing around with different things, it seems the top and bottom field are tied together regardless of alternative ticker URLs used, be that in the secondary, or source/pool fields, to the point that if i remove all of the info regarding currency conversion (the API key and GBP selection) it defaults to USD in the bottom field and will show a similar weird value, until you hide the top field, then it corrects, so it looks like you can't have top and bottom field visible at the same time
