The reason that the buttons don’t display the tables or the criteria is that the SQL was modified, most likely with an inner join.
To fix this issue you pretty much need to know SQL and remove the inner joins.
Example of SQL:
(with inner join)
Select
Student.FirstName,
Student
.LastName,
Addr
.Address
From
StudentTbl Student
inner join AddressTbl Addr on Addr.Id = Student.Address_id
------------------------------------------------------------------------------------------
(
without Inner Join)
Select
Student
.FirstName,
Student
.LastName,
Addr
.Address
From
StudentTbl Student,
AddressTbl Addr
where
Addr
.Id = Student.Address_id
