Max wind not reported.

A cold front last night brought 45-50 mph winds today. My Vantage Pro2 recorded a 49 mph gust but I’m seeing the maximum wind gust today on CWOP and Mesowest is 43. I have WD set to send 10 minute wind gust and data is sent every 5 minutes. If my station reports 49 mph why doesn’t this show up in CWOP?
