Label formatting going weird in CHOICES sheet

Hi,

So I just observed that my Collect app is displaying some labels in italic, when I have not defined any styling for them in the code. Is it because of some character length/limit of 'label' column in 'choices' sheet?

Here is the app snapshot:

And here is the snapshot from my coding (xlsform):

Thanks,

Now that I look at it again, it seems the double-underscores are causing the italic styling. Should not be happening though.
