Ion-segment-button not displaying texts

Hello guys…
I’m using ion-segment-button with texts & icons.

I followed a guideline here:

I can see icons displaying correctly inside my ion-segment-button but all texts aren’t displaying at all…
Why is this happening?
h2 tag, p tag, changing font color all don’t work in this case.
I applied the same back end from template.
Please help.

Thanks,

Can you include a screen shot?

And your code rather than the sample code?

And the output from ‘ionic info’?
