GA5 SE not playing full pattern

Hi, I am pretty new to GA5 SE. Hope I am able to explain myself here. So, I have an audio drum track that is about 4 minutes and 30 seconds that I want to bring into Groove Agent. So, I take the track, slice at hitpoints in cubase, and then drag the track to the c1 instrument pad in GA. It distributes it over all the instrument pads. Supposedly, when you go to pattern pads, it should create 1 pattern pad that will play all the slices in order and I can drag that pattern pad onto the GA track in my project. So far all that is good. The problem I am having is that when I go to play the 4:30 groove agent track, it plays fine until about 1:57, and the rest of the track is blank. Where is the rest of my track? I’m losing over 2 minutes of my song. Is there a size limit, or am I doing something wrong? It’s driving g me crazy that I can’t figure it out. Thanks for any help you can give me.

You might be running out of pads. How many slices is it?
