Loops won't loop

Never come across this in Garageband earlier but this new version is different, so I am sure there is some minor detail I overlook, but I have tried to find out what I may have done wrong, but cannot. First I added a "cycle" and wanted to loop it, but I could only drag it out to a certain extent and then I couldn't drag it more. Then I added several tracks with my keyboard and finally I wanted to add some Apple loops, but I cannot drag them out. So they won't loop.
This used to be as easy as that and you couldn't do it wrong. It was just to drop the loop on an empty track and start dragging, but somehow I cannot. So, anyone got an idea as to why not? Have I accidentally done somehing which I shouldn't? (I hate it when software do things for you!)

Glad for any tip.
