Tizen Developers

I have a button element as shown below:

<button type="button" class="loginbutton" id="buttonlogin" >Log in</button>

When TTS is on from the accessibility menus, the content is read twice.

I can see that, this issue is happening in a tizen 2.3 version tv and not in 2.4.

But i need my application to work in both.

Can someone help me fix this issue please ?
