You might try playing with the B screw adjustment. i'd try backing it out as much as you can without having the guide pulley hit the cogs.

I installed a Tiagra RDER on my hybrid, thinking it might shift my 12-23 cassette a bit better than the original Altus that came on the bike. Original cassette was an 11-32?
I had the same problem as you. I put the Altus back on and it's definitely better shifting. Doesn't make sense, but it is what it is.
