Hi!
Thank you for the proper ticket description and details!
The categories doesn’t vanish, if you look at the screenshot, a different taxonomy is selected. After saving it automatically switches back to the first taxonomy. If you select the “Product Categories” taxonomy then they will appear again.
As for the missing categories, these are indeed a “bug”, the category count is limited to 50 per taxonomy. The limit is used because some users had 10 000+ categories and the browser crashed when listing them. I’ve connected to your server via the sftp details and increased the limit programatically to 5000 per taxonomy. All the product categories should be visible now 🙂
Best,Ernest Marcinko
