Trouble with Arctic Explorer

[TechnicalPixel]

My map has everything shown for all three locations, but yet I haven't unlocked the trophy. What am I doing wrong?

Well I think you missed a spot near the bandit camp in Three horns divide
Before you can use the shop machines you need to collect 3 items 1 of them comes from another pump with the skags.

if you keep left you run across a little camp with a campfire and some lootboxes.

Go up there and keep walking towards the building behind another pump there are 2 badasses there.

If you killed them then continue towards the right you will go up a little mountain there you get some rakks and there should also be a named camp this one seems to be missed as it shows as not explored
I hope this helps.
