"Minimap" not showing all quest markers.

[No.]

I mean the thing at the top, the compass-map-thingy.

The map displays all of the markers that I've selected, but the "minimap" will show only two; one leading to the entrance of a dwermer mine -the one of the Lexicon quest, which I already completed, and where I have no other remaining quests-, and another one leading to... I don't even know.

Any ideas on how to fix it? I'd like to avoid having to install mods if possible.

Any mods? Sorted with LOOT? After running LOOT be sure to click on the button in the upper right that says "Sort" when hovered over, then click "Apply" once it appears.

I have a single mod installed, which is for the vampire dogs, so I doubt it has anything to do with it.

I'll give a read to the first link and follow its instructions. Thank you. (:

Just to be sure your load order in the data section of the launcher is
dawnguard
hearthfires
dragonborn
your doggy mod

sometime, there are quests where you have to find some stuff by your own, like the one where you have to find like 50 or 30 jewels that are layed around skyrim, but it s totally normal, and you have no help but fiding theses stuff by your own, your problem must be relied to that sort of quest

Followed the guide and it's fixed now. Thanks a lot, cfs. (:
