5.1.1 Android version Messaging

[AlphaBee]

Hi! Just recently updated my Sony xperia z3 to android 5.1.1. Everything's working fine but then i noticed that my sms message bubbles are transparent. The texts that I recieve still have solid colors. I thought it meant that i wasn't able to send it but it turns out that the messages i sent were successful. It's just that they're transparent. Been trying to lok for a solution in my settings but can't find any. Any ideas? Your help would be very much appreciated!
