Guild Wars 2

On the first day, I had the Crafting Mission,
but it didnt work when I refined 10 materials.

On the second day, I had the aquatic kill mission and healing mission
but it didnt work when I kill aquatic and even amphibia underwater.
and it didnt work when I revive the NPC, too.

On the third day, I had a dodge mission and healing mission
IT DIDNT WORK AGAIN when I dodge the attacks! :’(
but I can process the healing mission when I revive NPC on third day! o_O
(So strange, it work on thrid day, but didnt on second day!!)

I had asked my friends, they said they can just complete the mission by refining, reviving NPC and just dodging the attack as I did on these three days….

Why??
Are there anthings missing?
or I get bugged every day? :‘( :’( :‘( :’( :‘( :’( :‘( :’( :‘( :’(
