Does not recognize from Anspress

Hi,

First of all, this plugin rocks. Congratulations big time to the developer(s) !!
I have an issue though : I installed the Q&A Plugin Anspress , and its extensions that enable to attach categories or tags to each question : https://anspress.io/downloads/tags-for-anspress/

Yet Simple Tags doesn’t seem to see that these tags exist (it doesn’t appear on the list of possible sources hen I try to parameter a Simple Tag Widget), what should I do ?

Thanks for your answer ! ??
