Autocomplete suggesting unrelated or incorrect categories

On my website I have Algolia search implemented. However the autocomplete does not seem to work correctly. For example when I type in “iphone x” the suggested category is “Moto X” (+9 even more unrelated categories) even through I have a category named “iPhone X, 8 & 8 Plus” in my Magento categories. I can see from my Dashboard that the category has been indexed, so why is it not showing on my autocomplete?
