Data Entry post - strange error

Hi there - ran into something really strange.

I created a Data Entry test field - i'm inserting instructions - so replacing, "type your text here".

When I change the text and publish - the field is blank; however, the other data entry fields I've changed appear to be fine...

Here's an example - if i have the Data entry field text say "First Name:" - everything works fine.  When I change that text though, appears blank on publish.

Anyone else run into this funny error?

Thanks.
