A tiny quality of life fix to make auto-complete in formulas even better:
When you have writ a formula, like below, auto-complete helpfully suggest field names

and enable me to select the right field

If I need to change this field again, auto-complete again pops up the possible fields

However upon selecting the new field, I get this mess where part of the old field is intertwined with the new field, leaving an invalid fomula without manual correction
notice the 2 x Business
Would it be possible for the program to remove the entire old field, before inserting the new field?
