MATLAB: How to prevent uitab from printing UserData

appdesignerMATLABuitabuserdata

I have run into a problem with uitab displaying the content of the UserData property.
The following code
f=uifigure;
a=uitabgroup(f)
b=uitab(a,'Title','test tab')
b.UserData = 1:3;
yeilds this tab:
tab.png
The field with numbers is not listed in b.Children() and does not allow placing other GUI elements above it.
Is it a bug or that's how it is supposed to work? In the second case, is there a way to avoid this behaviour?
Thanks

Under 'User Data' in the documentation for uitab, it actually states:
Note
Do not use this property in apps you create with App Designer. For information on sharing data within App Designer apps, see Share Data Within App Designer Apps.
so you would store/access the property through:
app.Component.Property
the alternative is to stick with the regular figure instead where you can use the UserData Property
