Dear Andrea,
The search fields(Location, Range, Order By) in members page multiplies n number of times where n is number of fields added in bp-profile search form. Also, not sure from where does these 3 fields come from. Please find attached images


In the above 2 fields are added in the form so in members page fields (Location, Range, Order By) are repeated twice.
Below ref. I added 4 fields and found (Location, Range, Order By) repeating 4 times.


Thank you in advance!
