TP values on iOS not always editable.

When entering TP values on the iOS app, they aren't always clickable and editable. If you navigate to the 'chart' tab, and then back to the 'trading' tab when creating a new trade, then the TP values become editable.

It means when I'm adding a trade I have to click back and forth between the trade tab, and the chart tab, to 're-enable' the TP values.
