Copter Loiters for 50-60 seconds instead 5 seconds Delay in AUTO?

Hi All

Previously i was using AC 3.5.2 on my Quadcopter with
Pixhawk 1
GPS ublox M8N
Taranis X9E

But i deliver the quadcopter to my customer with AC 3.5.4 .
No Telemetry rewquired just live video .
I encountered a bug in AUTO Mission .
I use LOIT_TIME with delay of 5 seconds as first waypoint and then RTL.

So in AUTO Mode , Copter reaches Waypoint # 1 but it waits for 50-60 seconds instead of 5 seconds.
Does anyone has this issue before , kindly help !!!

Post your dataflash log mission file of you have it, and what GCS software you were using. Most likely a GCS bug.

I am using Mission Planner 1.3.52 build .
Unfortunaterly logs were disabled and i delivered the quadcopter to the customer.

Recently i have no copter ready to fly ,
I just want to know is it a known bug in AC3.5.4 or not ???

no known bug , I assume you mean MAV_CMD_NAV_WAYPOINT’s param 1 (hold time in seconds) - not RTL_LOIT_TIME which s close to what you mention.
if you can then reproduce and post df log.

There is WAYPOINT Option for mission Commands , i know it .

But instead this command i am using LOITER_TIME
