Categories not saving correctly

[jennymac]

Hi,
I have been creating categories for my library.
Even though I am choosing 'no parent', the categories are saving under another category as sub categories. If I go into them and change it back to 'no parent' and save, the message says save but the category is still a sub category.
I deleted and trashed one category and recreated it and it ended up being saved as a sub, sub-category,w hen I had chosen 'no parent.'
I have (hopefully) attached an image to show you. The category workshop equipment should be its own category. It was under toolkits so I deleted & trashed it, and now it is a sub category of pullers.
Any suggestions would be gratefully received.
Thanks
Jenny

Hi jennymac,
are you using Abook 3.1.0?

Hi Fredrica,
I was not, so I installed it but the issue is still happening.
