Once the pads engage the discs, there should be very little additional travel. Perhaps only one disc is being grabbed, and the other has additional travel that is preventing the firm lever.
Are we sure all of the caliper cylinders are full of fluid?
If I may make a suggestion, just from my own understanding, but please make sure it's not a bad idea?
Now that the calipers are as full as they are, what about removing each one at a time, and using the pads or other spacers to make sure no pistons pop out, squeeze the pistons back into the calipers as a form of bottom-to-top bleeding.
As long as the volume of the calipers exceeds the volume of the lines including fittings, the lines should be fully air free.
The MC should be level and the fluid level be kept low and watched to avoid spills, and protection provided anyway. Any air left in the caliper cylinders would be at the top area, which should bleed more easily.
Logical?
