Scope isn't showing all data points

My scope isn't showing all data points and is just interpolating values in between. I have attached three screenshots, one of the audio signal plotted in MATLAB workspace, one of the block diagram I am using to transfer the timeseries 'finalaudio' to SIMULINK, and the last one being the output of the scope.

The scope worked perfectly for two minutes, but now it doesn't. I have no clue what settings I changed (I don't remember changing any) or how to fix it. Please help!

Also, simulation time has been chosen as the length of the audio signal i.e. 2008924.
