I am using filter formula below. The formula works fine the first time, but once it filters the result properly, it corrupts the same formula in next row below with --.
=iferror(FILTER(PROVEEDORES!C:C,PROVEEDORES!B:B=C252),"--- No Existe ---")
How can I fix it?

--? When you look what's in the cell, you'll find out it says something like this: `=CONTINUE(C2, 2, 1) – Jacob Jan Tuinstra Jan 10 at 20:01
