Problems in updating

Hi, I am new in wordpress. I face some problems when updating my wordpress.
Firstly, I had added new products in my product page however it does not appear when I enter the homepage. However, if I enter the direct link on the address bar, the page appears.
Secondly, I tried changing the Product Categories name, it doesn’t update too.

Anyone know how to troubleshoot?

Please help! Thank you so much!
