How change Flight# in PIREP Logbook...

Yikes! I made a mistake in my flight logbook and don't know how to correct it. Here is the problem: PID#697. Flight# 900021 is actually supposed to be Flight# 900022 and Flight# 900022 should be Flight# 900021. As part of the AK Marine Hwy System Tour these two flights are shown "out of order". Being as I don't want to be "Out Of Order" in Alaska, I would be forever grateful if someone with more knowledge than me could correct my mistake! Thanks!

Thanks for fixing my blunder...now I'm no longer "out-of-order" in Alaska!
