I would try reinstalling BiteSMS from Cydia. I would just reinstall on top of the current application; I'm not 100% sure, but I think that the original will be deleted during the reinstall.
I haven't had any problems with BiteSMS and I've never seen what you're showing us, but the reinstall has worked for me with another application. Remember to respring your device and if that doesn't work, try a "hard reset."
You can find all of your Cydia downloads under "Manage" and you can reinstall them on to your iPhone at no charge.
