Cheers got it working with this
/usr/share/tvheadend/src/webui/static
sudo -s
cp tvh.js.gz tvh.js.gz.orig; gunzip -c tvh.js.gz.orig | sed 's/RegExp.escape(r.get(this.valueField))/RegExp.escape(String(r.get(this.valueField)))/' | gzip > tvh.js.gz
Yeah the TVH built into OSMC comes from their online store, so dont knwo if theres any implications to removing it and installing it from TVH directly
