You are right:
All ground markings alongside RWY 36R/18L are wrong: they say 36L/18R
Also, all ground markings alongside RWY 35C/17C are wrong, they say 35L/17R
Taxi signs look correct.
Feel free to reports those issues here: MSFS 2024 Airport / Helipad Issue Tracker (using instructions provided in the 1st post).
