AX-15 rpm issue when cold/hot

1999 Cherokee, 4.0L, AX-15.
Supposedly "new" clutch (15K miles) according to previous owner.

When the engine is at operating temperatures and upshifting, my engine RPMs drop to idle and must "bounce" back up to the appropriate speed when i depress the clutch. I've been adding some throttle to compensate for the drop but it takes some concentration and I need to be slow with my clutch release or it is a rough engagement.

When not at operating temperatures, I do not have this issue. It is so smooth, easy, a joy to drive because the rpms slowly drop to the desired rpm when upshifting.

Any advice?
