UPDATE 10/18: This is a REALM ONLY PROBLEM. When REALM downloaded to local computer SIGNS work just fine.

Writable BOOKS in the REALM work fine. SIGNS do not. Are there different Keyboard input routines where SIGNS still treat numbers as math?

What does PC 1.13.8 mean?  Is this JAVA only stuff? My Win 10 Bedrock is 1.7

How to I tell you this is Win 10 Bedrock REALM ONLY in your   "Affects Version/s:" Field Dropdown?     

Do REALMS have versions?

 Summary - Multiple Problems with SIGNS on BEDROCK WIN 10 REALMS

 See Comment Number One and Comment Number Two for Detailed Examples about the SIGNS

Typing Numbers (or dashes) at the beginning of any of the lines on a four line sign in Win 10 Bedrock on a Realm causes the final sign to end up blank (all typing lost, blank sign on wall). Typing numbers in middle gives one line sign.  

Comment Three: Sometimes only 2 - 6 letters are places on final sign. Should I be keeping track of times and days of the Week?

(Suggested solution, internal representation of numbers should be Text on a Minecraft sign (not numeric). I have no need to do math with numbers on my signs.
