Unlock in-app purchases in UG Tabs app if you've already purchased them separately

#1
Is there a way to unlock the Guitar Tools or the Tabs Pro in-app-purchases in the UG Tabs app if you've already purchased them as separate apps? It seems weird that when I try to use that functionality in the Tabs app it asks me to purchase them again.

Does the same thing for me, wish someone could help.
