Signs not going to next line

Hi, just would like to report a bug i have noticed while playing minecraft pocket edition on my samsung galaxy j5 android 6.0.1. While typing in a sign clicking enter would normally take you to the next line. However, in my case it did not. Also if typing in the same line continiosly appears to work fine until leaving the writing and it appears as one line. Not 100% sure if it's my phone but it only happened onced updating to the beta. Maybe something to look into?

Thanks
