One more data point. I'm having the same issue: I tried to enter the following text onto a sign...
T H E B I G D I G Please don't dig for now. Danger abounds!
As soon as I click "Done", the first line disappears. I can type 4 characters on the first line and they'll stay, but a 5th character causes the first line to disappear.Correction: I can type as much as I want, but as soon as "Big" is on the line, adding a "D" causes the line to lose its text. I'm now assuming this is a malfunctioning "bad language" filter.
