Saudis don't like how close to Iran they are. Its a pure political dispute regarding the two rivals in the area, Saudi Arabia and Iran.
You notice who supported them? Iran and Saudi Arabia. They are ideologically different powers and hate each other and yet they supported the same groups. This hate to do with the war, and how it really got out of hand. Of course they are supporting religious fanatics. Muslims were being targeted, it became easy to make it a holy war.
How does this compare to Albania though? They had a benefit there in supporting Islamists in Bosnia because of the war. What benefit is there in Albania? Al-Qaeda in Yemen and the IS attack the Saudis there all the time. Why support jihadists who end up joining their groups? so more of the Saudi's own soldiers can die?
Turkey isn't a US enemy and that still doesn't show the Albanians are going to betray the US.
Afghanistan isn't WW2 or Korea. Greece has no experience in fighting a large insurgency like the Taliban. And it looks like Greece did send troops. Less than 200 though and mostly in security or training. Meanwhile the Albanians have circulated about 5000 or more soldiers through Afghanistan. Completing over 120 missions and actually participating on the ground against the Taliban.

Greece couldn't even be bothered to send more than 200 soldiers.
Tarnishing the US's image around the world and making themselves look like thugs is worse.
Thats the Saudis.
Albania's air force is too old and they are getting rid of it and attempting to modernize it. Thats why Italy patrols their space. Greece is second in military spending in terms of GDP. In terms of dollars, they are behind 11 other countries in military expenditure and don't have the same military capabilities as other countries even if they spend below 2% of their GDP on defense.
