Product Category List Issues

Hello,

Updated all plugins
Cleared all cache.
Woocommerce 3.3.5

There are a few issues…
1) Product category list no longer shows sub-categories automatically.
2) If you look at the sub-category list (books) quite a few sub-categories are now grouped into one line? Therefore the list is not showing in a list properly anymore?

Please help!
