Sage 2023 - F2 Item lookup on Sales order

Our Sage 2023 has an issue with some users.

When on a Sales Order, in the Lines tab, typing a couple characters and pressing F2 will display items which begin

with the entered characters.

For some users this does not work.

We have tried making a new defined default search with the correct parameters selected when defining the search, but the

search still show no results when pressing F2

Any suggestions will help
