views – Drupal 8 – Rule: add a condition to the selection by drop-down list

I have a drop-down menu in a node and the id's drop-down menu is "field_b_status".
I want to add a condition to a rule if the value of the drop-down list is equal to one of the "Full" values, then send an e-mail

When I try to add this, I see the error.
Field_b_status.value data selector for the context The data to be compared is not valid. Can not get field_b_status variable, it is not set.
Please see the screen capture:
