Via Structure on Bottom Layer

I can create Via structure on top layer by open "Route>Via Structure>Create>Standard" and then use fanout tool to add it to my design. 

But for bottom layer I follow same routing. create a trace on bottom layer, create the Via Structure and use fanout.tool but I cannot add Via structure on any bottom pin.

ERROR:

E- (SPMHGE-633): Library via structure BOT subclasses don't match to command parameters. Via structure can't be used.

I Know that starting layer should match with Via Structure and I verified that my created Via Structure is on bottom nevertheless I get the error.

Please heeeeeeeeeelp. I have more than 1000 pins that need this fanout!

I Use Allegro 17.2 HotFix 042
