Hello Chong!
So far, we have not had a problem with the Woocommerce plugin.
What version of the theme do you use?
Maybe you just need to Setup the slider in the right way?
To enable the sliders on the specific pages, you will need to :
1) Go to the page where you want it to appear, (Dashboard ->Pages ).
2) Select the desired page.
3) On the Agama Options menu at the bottom of the page, open the “Slider” tab.
4) Enable slider on “Enable slider” drop-down menu.
5) In “Select Slider” drop-down menu, choose Agama slider.
6) Click on “Update” button to save the changes.
