Autocomplete search doesn't allow user to pick from list

[AnneMorrisMC]

I have three autocomplete searches in a row. The first allows the user to pick a building, then floor, then room. The cloud in the search bar constantly blinks and doesn't allow the user to actually select a value. I know the list is being made and that there are less than 2k records, but it still keeps blinking. Does anyone have a suggestion? I don't want to have to store a static list of rooms. I want the survey to reference the feature layer that is updated.

autocomplete search("Units?url=https://xxxxxxx/mapping/rest/services/Indoors_Services/xxxxx", "contains", "NAME", ${unitid}, "LEVEL_ID", ${levelid}, "optimize=true")
