Cub Cadet LTX1050 center blade not cutting

Cub Cadet LTX1959. Was cutting fine. Then I sharpened the blades. I know I put the blades on correctly and they are tight. Now when I mow tall grass the center blade is leaving a trail of tall uncut grass. The only thing I can think of is a loose belt, but wouldn't that make all blades cut bad? Can a loose belt somehow make only the center blade cut bad?

I guess the center spindle could be sticking... I don't know. Strange.

Also redouble check that the middle blade is on correctly, and that the lift wings face upwards and not downwards. Also, I have seen many home sharpened blades having a rounded off end, instead of straight. This will allow grass to "roll" off the blade instead of getting cut properly at the outer tip of the blade. Take a pic of your blades and post it please. Worn, not properly sharpened(there is a correct and not correct way to sharpen them) and even upside down despite owner swearing they are on right are things I have seen in 30+ years of professional lawn mower repair. Even missing or damaged internal shrouds on the mower deck and grass build up can also make a deck cut poorly on one or more blades.
