Can combined & free chlorine go up if no diclor or chlorine or bleach is added?

I have a 400 g. hot tub and measure FC and CC with a Taylor k-2006 kit with MPS correction regent R-0867 AND a Hach strip.

Both Taylor k-2006 kit with MPS correction regent and Hach strip show increases in CC from 2.0 PPM to 4.6 AND FC from 1 to 1.8 in the past few days but I have NOT added dichlor, chlorine or bleach. I've only added PH down, Alkalinity UP and MPS. Should any of these INCREASE the FC and CC?

I use Nature2, MPS after every soak (daily) and weekly addition of 1 cup...

Can combined & free chlorine go up if no diclor or chlorine or bleach is added?
