Uncaught ReferenceError: _ is not defined

[kdschmidt1]

every change on the configuration page leads to:
ConfigureCell.jsx:44 Uncaught ReferenceError: _ is not defined
at r.value (ConfigureCell.jsx:44)
at Object.d (react-dom.production.min.js:15)
at y (react-dom.production.min.js:15)
at b (react-dom.production.min.js:16)
at x (react-dom.production.min.js:16)
at P (react-dom.production.min.js:17)
at S (react-dom.production.min.js:17)
at _ (react-dom.production.min.js:17)
at zn (react-dom.production.min.js:81)
at ue (react-dom.production.min.js:285)

any idea how to solve this?
