Clutch pedal stuck to floor after clutch job

Months ago, I unplugged the clutch hydraulic line going into the slave cylinder when pulling the transmission as part of a clutch disk replacement. I remember at least a cup or two of fluid coming out. Today I hooked the hydraulic line back up to the slave cylinder and bled the clutch with a Motive Power Bleeder. However, my clutch pedal is still stuck to the floor. So I'm trying to diagnose the issue.

I followed the procedure in the Bentley manual for the clutch bleed (hopefully). A few notes:
- During the clutch job, I replaced flywheel, clutch disk, throwout bearing

- As first step in the bleed I pressed the clutch pedal to the floor by hand. It wanted to snap to the floor, as the the manual mentioned would happen: "As there is no system pressure, servo kinematic effects will cause the clutch pedal to move forward abruptly. In order to avoid damage, the pedal must be guided manually."

- I haven't started the car yet or pumped the pedal except to test it once after the bleed. I thought after the bleed the clutch pedal would operate as usual, but it still sticks to the floor.

- The Motive bleeder I used came with a broken pressure gauge, so I'm not sure of the exact pressure I applied.

- About 12 oz of fluid came out the bleeder valve of the slave cylinder. It took ten minutes or so of bleeding for this amount of fluid to come out. After about 5 minutes, I saw no more bubbles but kept going to make sure.

So I'm trying to figure out if this pedal should still be sticking to the floor. And if it isn't, where could I have gone wrong?
