Kind of common..... back bleed the system... that is, use a syringe to push fluid from the slave to the master..... after you get lever feel, bleed as normal one last time

How does this slave cylinder work ..it pushes that rod in the center? Is that rod supposed to be held in..mine is just free I pulled it all the way out..it seems to go from end to end of case.pushing on it doesn't seem to do anything.

Slave cylinder on the left side pushes the rod though the case into the clutch assembly on the right side

That's a really clean setup. Just did mine for the 2nd time and it was caked with awful black gunk.

FYI, brake fluid is very caustic to paint and powder coat. If you get any on anything, clean it off rather quickly if you want the finish to stay pretty.

Does the slave piston move when you squeeze the lever SLIGHTLY? If so, are you sure you got the piece that goes into the throw out bearing in the correct direction? It's the piece that the rod pushes against to push the bearing that in turn pushes the pressure plate to separate the plates. I had a friend, or was it me?, that left that part on the bench and couldn't figure out why the clutch wouldn't work after days of bleeding and futzing around! LOL
Then there it was on the bench! Let us know what you find.

Yes the push-rod just slips right through the cases until it pushes on the lifter. For nice smooth action make sure the rod is polished smooth and greased.

You should be able to bleed the slave with it off the engine, using a g-clamp to hold the piston still. Air does like to sit right in the master, try wiggling the lever (small quick moves not big pumps) to encourage it to move. I've seen fine bubbles rise out of the bleed port in the reservoir when I do that. But until you get fluid into the piston area, you won't be able to pump the line free of air.
