Hello @jesslucyg,
Thanks for the review.
The cache plugins are usually causing these kinds of issues. You have to purge the cache after each change, or even disable it because (sometimes) the purge mechanism is not working correctly.
Could you please tell me your hosting provider? I am asking because it usually happens on GoDaddy/Sucuri and BlueHost, and unfortunately, we have no control over it.
