Using input groups, additional styling may be necessary to correctly display error icons about formsy-react-components HOT 1 CLOSED

Verified, but not going to do anything about this in this package.

It's mentioned in the Bootstrap 3 docs;

Icons, labels, and input groups
Manual positioning of feedback icons is required for inputs without a label and for input groups with an add-on on the right. You are strongly encouraged to provide labels for all inputs for accessibility reasons. If you wish to prevent labels from being displayed, hide them with the .sr-only class. If you must do without labels, adjust the top value of the feedback icon. For input groups, adjust the right value to an appropriate pixel value depending on the width of your addon.
