Hi Chris,
thanks for the report but it looks like a Zibo issue than a navdata issue because the BLV transition for the ILS12-Z approach are included in the data. Here from the corresponding lines in the XP11 dataset, which will be used by the Zibo addon:
You see the yellow marker, thats the transitions BLV with the procedure-turn. So, the navdata contains this transition. Please report this to Zibo … sorry for that.
