RTL Continues After Rearming

This has happened twice. I activate RTL mode just to check it out. There was no issue happening on both occasions. I have RTL set on a separate channel /switch (channel 7) in mission planner. My other 6 modes are set using channel 5. After rearming and take off the drone initiates a landing mode where it does not accept any throttle command and just lands followed by a shutdown of motors. It does not return to where it was armed. GPS working and active during this time. I don't have the Landing mode as a selection in mission planner.
Wanted to add after the initial RTL I re powered the quad prior to arming again. What I haven't tried was a reset of the Pixhawk unit. It almost seems that the Pixhawk doesn't clear the landing command from the RTL mode being activated even after re-powering.
Both times this happened was a few days between each other. Wondering if the memory of the Pixhawk is not being cleared with the re-powering.
 
I'm not familiar with the Pixhawk, but if it continues to do this after shut down and re-arming, and it's not returning to it's home location, this sounds more like it's going into failsafe, not RTL. Do you have an OSD that shows you what mode you're in when this is happening?
 
I agree with it seems to be going into failsafe. The thing is I have failsafe set to go to RTL and not just to land. I was not monitoring OSD when this happened so not sure if it did show failsafe activated. I haven't checked yet this time but last time there was no entry in the logs showing failsafe.
 
I reviewed the logs and my drone did go into failsafe for a battery setting of 14V. I guess 7 min flight time is good for a 550 with a tarot gimbal with a gopro running a 4S 5200 battery.
 
Many variables, but 7 minutes would be typical. So with my Naza, it will return to home position when it goes into failsafe. BUT with low voltage protection, it will give me an audible warning at 14.8 V, and at 14V it will just land without returning to home position. So I guess what I'm saying is that failsafe and low voltage are 2 different protection systems
