Bug with Hidden blade and Squire

There's a bug with using the hidden blade and squire at the same time in the current league. the support gems in squire does not effect hidden blade like it did on previous league and on standard. i put the greater multiple projectile support gem but does not increase the number of unseen strike.

This is not a bug.

There is a reason support gems in your shield would not be expected to apply to Hidden Blade;
