Hi!
It’s most likely due to a jquery ui javascript confict. My suggestion is, that you should switch the template temporarly to default and see if you can use the controls. If not, then it’s probably another plugin causing it. Well, there are so many plugins, that I’m unable to tell which could cause it, so the best option here is to temporary deactivate some of them (or all of them), configure the search, and activate them back.
This issue happened once before a long time ago, it was an outdated free plugin causing the problem, but I cannot recall which one exactly. Anyways, temporary deactivating some plugins or swicthing the template should definitely help 🙂
Let me know!
Best,
Ernest
