Symbols Stopped Functioning with Keyboard

With the latest update, (beta user), the main symbols on the keyboard have stopped function. When a key press is held, the symbol pops up, and appears to work perfectly. But when you let go, it does NOT insert the symbol. If I open the symbol drawer (123) they work fine, it only affects long key press symbols.

The issue is intermittent, and restarting the phone resolves the issue for awhile, but eventually will still do it again.
