Nothing to see here. Move along.

I have fixed the shift problems of the longer lever that shifts down (smaller to larger cog), but the smaller lever that shifts up (large to small gear) carries the larger lever lever with it. In other words I can't shift the smaller lever buy itself. It does actuate, but it doesn't move independently. To shift it, I have to hold the larger lever and push the smaller lever. It has done this before and I dealt with it and it wasn't really an issue as I wasn't racing and need the quick shift.

I hit it with more WD-40 to see if I can further address it. We'll see tomorrow.

The symptom you just described sounds like a broken-off tip of the anti-carryover latch, which is actually part of the small lever, up past it's pivot point.

This is the death of so many 9s brifters, I can tell you.

On some occasions, however, where there is noticeable gumminess to the small lever's action, the small lever can get "gummed" to the big lever.
Diagnostic for the latter condition is the temporary application of heat or WD40 to this pivot region, which, if not remedial, signals the need for a new brifter.

The tip of the small lever gets broken off when the two levers are accidentally pushed forcefully at the same time, since the anti-carryover latch is supposed to prevent the large lever from moving when the small lever has already moved a small amount. Often this happens under stressful riding conditions, or when poor cabling masks the high effort that it takes to actually damage the latching tip of the small lever.

Cannibalizing parts from a similar shifter with a different issue/failure is the only way to fix this problem.

So I went out for a ride today after many WD-40 and relube cycles on the brifter. The good news is that the downshift (smaller cog--> larger cog) is fixed. The bad news is the reverse (small inner shift lever)is shot, It moves a little but then starts to bring the larger lever with it and not shift/catch. If I hold the larger lever, I can move the smaller shifter and shift.

So I need a new brifter, but at least I can make it "work" for now.
