The search dropdown returned the wrong encoding (instead of the description field) when the list of values was set after setting hidekey = [true]; in Aurena

On an IFS Cloud 23R1 new page ,we set hidekey = [true]; to a lov field, and the filtered dropdown box selection functioned properly(Correctly return the value of the description field when the user selects an item), but the search function dropdown box at the top of the page returned the code, and as a result, the search function didn't work well.

I think it's a bug, I wonder if anyone has solved this problem, any useful advice would be greatly appreciated!
