How did I-TASSER get 12 helices for a protein which on Interpro shows to belong to 7tm_7 family?

Sir,

This is Nidhi Gujar from Institute of Bioinformatics and Biotechnology (IBB) , Savitribai Phule Pune University (SPPU).
I'm currently working on a project of modelling the gustatory receptor Helicoverpa armigera Gr9 (HarmGr9) which according to Interpro and Pfam belongs to 7tm_7 family.
Also when I checked with other tools like TMHMM and SACS-MEMSAT it shows 7 helices.
I had submitted the amino acid sequence of this protein to I-TASSER few days ago. But the predicted models consist of 12 helices.
So you could you please explain how is it been modelled as 12 helices?
My job ID for I-TASSER was S285388.

Thank you.
