IIRC it is easy to accidentally miss the lifter and drop the rod to the side of the lifter. Maybe more so on the lowest lifter. Can you use a magnet to retrieve the rod, and try again, to see if the lifter is really collapsed?
If you replace one lifter, replace them all, if you replace the lifters, replace the CAM as well!!!!!! At that point, you might as well replace the timing chain and gears, and have the head serviced, and new valve seals installed!!!!
Also be sure and use a high zinc, ZDDP, break in grease on the bearing surfaces and a high ZDDP break in oil.
