I had a leaky heater hose quick connect i swapped out with little issue making sure not to damage metal hose. Decided to do flush as well with distilled water disconnecting lower hose only from engine side, not radiator side. I think i flushed 4 times. Afterwards, i seen this leak In the back of engine bay near a cylinder and metal hoses. It leaked worst with heater on. I checked car in morning and seen the reservoir slightly lower from top, i may have over filled a little. Will check again today but i would hate to think something else is wrong. I was very gentle. Here is video after flush done.

Looks also like it could be water build up /condensation from your AC. mine does the same when running the AC more when its humid outside.

THANK GOD! I was getting so upset that a new issue would come out of nowhere and didnt know how i was going to get back there. I ran the heat on highest for a descent amount of time in hot weather and switched to cold too. Plan to check reservoir to see if it went further down but I believe you have to refill a little after first flush?

Did you ever find a leak or was it just the condensation

I checked the reservoir and it definitely went down. I still see leakage from that area too. I am still testing but recently when I checked, the line didnt move. Im hoping the movement initially was because of refill and they say to monitor so you know when all bubbles out system. Will definitely be checking today.

Just wanted to update that the reservoir level doesnt seem to be going down anymore. The condensation idea sounds legit. Will update you if I see this still being a problem.
