Autocomplete rule does not trigger configured error message

Summary:

We created an autocomplete rule with the following condition: When adding or editing a contract extension with the type "fixed term", the user should receive an error if the total duration of all contracts with the type "fixed term" exceeds 1096 days. 

This rule triggers correctly when editing an existing contract extension. However, when adding a new contract extension it does not trigger the autocomplete rule error message, but instead it shows another error message.

Customer: Ziggo Services BV.

Use Case: #47

The issue appears when selecting the "+Add" option to add a new contract extension.
