Can't get to ANY time leap quests. Please help

I was level 6 when I first knew about TLQ. Didn't do any time leap quest

Now I am level 9, and the screen of "time leap quest" was abruptely closed by a stupid message in the screen. Now I didn't complete lvl 4 time leap and can't know how to complete level 9 time leap quest. How the hell can I complete those 2 quests? Can't find ANY help ANYWHERE. I have NO MARK in the map that points to a time rift. Please help

I didn't know there was gonna be a char wipe next week... thank you for this information, btw I found the way to do these time leap quests, so thank you very much.
