Multi-Select Text box has text stating ""select up to 20 choices"" below the field. How can I get rid of this?

It's still there - I probably have it on other forms as well, but I just noticed it today (12-3-17) when creating a new form on a new table. Only five choices, and that's all we will ever have. Would dearly love to be able to hide or remove this within native Quick Base without having to resort to coding or a Service Provider.
