Hi Hunar,
2 things to try:
#1 see what's your default operation on the form (See Catalog-Entity->Edit see the column default. IF none f that is checked then the 1st entry is the default) and that operation gets executed (also depends of your Form Type (Edit, Display, New..).
#2 add condition to your stored procedure (if you use the to interact with the data).
Please let me know how that goes.
