I'd let the pool circulate at least 24hrs after adding salt before taking a salt reading.
I expected answer like this but couldn't resist
is it normal the salt reading to lower or to rise after first 24 hours?

TA is ok for now, it will probably drift down on its own. If you want to lower it here is how, Lowering Total Alkalinity.
Did you run your pump 24hr to help dissolve the salt? Brush it around when you added? If not then it could take a little longer. Level will not lower after 24hr only rise.
