Note that the ammonia test does not distinguish between ammonia and monochloramine. Nevertheless, even if there is monochloramine there, it pretty much had to originally come from ammonia before you added the chlorine (at least for the relatively large amounts you are seeing).
So basically if you opened with ammonia you could have read zero in the CC test though if you had tested for ammonia you would have found ammonia. After adding chlorine, it combines with ammonia to produce monochloramine and that shows up as CC and still shows up in the ammonia test (because the ammonia test technically adds Dichlor to the sample to create monochloramine and what you are measuring is creation of a dye from monochloramine reacting with salicylate and getting oxidized further). As you add more chlorine you may find that the CC keeps rising as more monochloramine is formed quickly until you've close to exhausted the ammonia. At that point, additional chlorine will oxidize the monochloramine and both the CC and "ammonia" (really monochloramine) will drop.
The units of measurement for CC are 5 times higher than for ammonia so what looks to be around 2 ppm ammonia (as ppm N) would produce around 10 ppm CC. That will take not quite 10 ppm FC to get rid of so you're almost there (though that image might be 4 ppm ammonia in which case it would take more like 20 ppm FC). At any rate, you just keep adding chlorine until the CC goes away and the FC starts to hold without loss overnight.
