No values in fields in new forms or queries, only ids (1 Viewer)

I have database for orders. Tables are Orders, Sales person, Customer and Products.

Problem is that suddenly values aren't shown in fields if I make new query or form. Values are shown in forms which I have made previously.

I was testing different options for user's main form. I was testing form with subform and split form.
Form with subform I made previously and it is working. In this form I have buttons on main form and subform is containing Orders table in datasheet mode. No problems with this, I can see values in fields.
Split form I have Orders table in datasheet mode, form mode is hidden and buttons are in form header. Suddenly I noticed values aren't showing anymore, only ids. This point I was making macro to open record on click. This macro is working.


What I did to cause this? Any help where to look for the problem?

don't use a split form.

use 1 master form (single record) the Order,person, total
and a subform (continuous) that has every Item,Qty,Cost, ExtCost

The Order Total is a textbox on the subform footer: =Sum(ExtCost)
you cannot add subform items until the Master form record is saved 1st.

I deleted the split form. If I make a new form or query from the Orders table values are not shoving, only ids.
Why the previously made form shows values but new ones does not?
