I am running into the same issue now, but with the “Hours” field. I’ve got the latest versions of the SLP plugin (4.5.09) and the Experience add-on (v.4.5.08).
I also noticed that the “Hours” field will not display at all unless the “Show Hours” field is checked under the results tab, even though I have the shortcode in Results Layout field. Seems like any attributes I put on this shortcode are overwritten by those applied by the plugin (store-locator-le/include/class.ui.php, line 883).
Is there some way to overwrite these attributes?
