Previous legend replaces the new one in a plot, why?

In an app (desgined using Matlab), I plot x and y-data and clear axes using 'cla' in order to plot a different x-y data. The issue is- the legend from the previous re-appears on the new graph replacing the new legend. I can not understand why. I want to completely remove the legend for the first dataset and prepare the same axes for a new data. I have tried using other functions as well but it does not work. Any help would be appreciated. Thanks a lot.

Were you changing the location of the legend as shown below? I made a quick app (attached) using the approach below.
plot(rand(10,1),rand(10,1))
hold on
plot(rand(10,1),rand(10,1))
legend({'example';'example2'},"Location","west")
cla
plot(rand(10,1),rand(10,1))
If that is the case, you can create a handle for the legend and delete it after clearing axes.
figure
plot(rand(10,1),rand(10,1))
hold on
plot(rand(10,1),rand(10,1))
L=legend({'example';'example2'},"Location","west");
cla
delete(L)
plot(rand(10,1),rand(10,1))
legend
