Default [Q] Xperia V phone dialer app issue

I just found a bug in the dialer app. When dialing out to a IVR system, after connected I'll bring out the keypad to key in something. But the numbers I key in are not displayed on the screen. For example, if I need to input my credit card number, it'll be very frustrating because I may get confused of which number I just press.

I'm using the latest .199 firmware. Anyone else notice this issue?
