Sequencer not playing all shots

Hi,
I combined multiple small shots into master sequence. In the master sequence, the first shot is playing, but the remaining shots are not playing. But when I play them as individual shots outside the master sequence, they are playing fine.

Can someone please help me fix this, I much appreciate it.
Thanks in advance.
Regards,

Maybe put them on one line?

No. I tried. It didn’t work.
