Macbook safari history clear button greyed out
I have a MacBook Air version 10.15.1 and am having trouble clearing safari history. I like to clear history to keep things clear and tidy. I went into safari history to clear history and in the corner next to the search bar there is a clear history button that is greyed out. I am also unable to clear it from the dashboard up top and am unable to select and delete sites in history. It would be great to know if I changed any settings. I have been looking for ways to reset history or safari settings but all of them are either are too old for my version or are not helping my situation.
