Hi

I have been trying out some fighter multiclasses, but i have found when i pick the "superior technique" fightingstyle i do not get an option to pick my manuver and the superiority dice does not apeare in my sheet. 

Can this be looked into, and does anyone else have this problem?

This has been an issue for a while. I first observed it...I don't even remember, I want to say a year or more ago. It surely existed long before even that. (I don't roll up martials too much, lol.)

I unfortunately don't know of any workaround for this, short of just using the Notes section of the sheet to jot it down yourself.

Sorry I can't be more help - but to answer your questions, yes, it is a problem; and no, at this point it probably isn't going to be fixed. (Or, maybe it would be more accurate to state that if it is ever fixed then I'll be pleasantly surprised. It seems unlikely at this point, but I guess it's not impossible.)

This is a known problem. The workaround is to create a feat using the Martial Adept feat as a template, renaming it to match the fighting style, and add it directly to the character sheet.
