When accessing the Event Management API, I encountered an issue related to custom Multiselect optionsets. I updated the Website entity configuration for Event table with the custom selected fields in JSON format, but it seems like the multiselect optionset values are never returned in the Event API response. Boolean optionsets work but something is not right with multiselect optionset. I have published the new custom forms but I still do not get the fields. Is this a known issue or not?
