Electrical Wiring in the Home/Switch/light wiring

The blk wire you have on bottom of switch is actually wire for light that is working off of switch. It is not the power wire. The power wire is one of the wires in the pigtail attached to the top of switch. This is why one of your lights is staying on constantly. Turn off breaker remove wires from pigtail cap the blk wires individually w/ wirenuts. Get test light turn on breaker uncap one wire carefully test it with light. If it lights up it is power wire mark w/ tape. Then recap it, test other blk wire it should not light up. The wires that test no power goes together in pigtail on top. Power wire on bottom. All other connection as you had them.
