Cannot colapse main category when in child

Hi,
Thank you very much for this wonderful plugin. I have a little bit of trouble and I was wondering if you can help me out. I have a site in this format: Category > SubCategory > SubSubCategory > Products. Everything works ok when you are in Category with only following options activated: Show hierarchy and Show as Expand/Collapse but with same settings when you are in Subcategory I cannot collapse to Category, and insted of showing “-” it’s always showing “+” even if subcategory are expanded. SubSubCategory works as expected. For better definition please visit: https://navigatia.ro/c/navigatii-dedicate-auto/ and https://navigatia.ro/c/navigatii-dedicate-auto/alfa-romeo/
