Maybe you had better employ just one plot() and hold it to plot all imported data from audio files, e.g.:

plot(y), hold all  % That will be held and all of the imported audio data will be plotted in a different line color

handles.srcFolder = folder_name;
dinfo = dir(fullfile(folder_name, '*.wav'));
filenames = fullfile(folder_name, {dinfo.name});
nfiles = length(filenames);
AudioArray = cell(nfiles, 1);

for k = 1 : nfiles
   thisfile = filenames{k};
   [~, basename] = fileparts(thisfile);
   [thisaudio, thisfs] = audioread(thisfile);
   AudioArray{k} = thisaudio;
   FsArray(k) = thisfs;

You did not change

t = (0:size(thisaudio,1)) / thisfs;

t = (0:size(thisaudio,1)-1) / thisfs;

like I said to do yesterday.
