invalid value for Float(): "50 100"

I followed the guide on how to set up action text with administrate gem

https://github.com/thoughtbot/administrate/wiki/Field:-RichTextAreaField

https://github.com/thoughtbot/administrate/wiki/Rails-6-&-Webpacker

I successfully implemented all the code.

On the administrate admin, I get this error when I want to view any record with action text custom field

description: RichTextAreaField All the other models without rich text works with no issues ActionView::Template::Error (invalid value for Float(): "50 - 100"): 16: [1]: http://www.rubydoc.info/gems/administrate/Administrate/Field/Number 17: %> 18: 19: <%= field.to_s %>
