drum loop continuous playback?

Hi

I wonder can anyone help me?
I am using FL STUDIO 20 producer edition,
the problem I have is when I put a drum loop pattern using Konkrete with Kontakt 5 player on a channel rack and put that pattern on my playlist it plays continuously throughout the track,
I would like to change the loop up for variety on my track, and maybe clone it to change it around, I can stop and start & change the bpm within FL Studios but once I hit play on song mode it goes on playing the same loop from the start & throughout the entire song, even if I bring in the loop on a pattern on the 4th beat?

so basically, I want to bring in my loop in somewhere other than at the start of my track, but if I hit play song, the loop starts at the beginning anyway no matter where I place the pattern?

the same problem occurs even if I use a standard FL STUDIO drum loop

any advice or help would be greatly appreciated

thanks you
