PLEASE CLOSE FOUND THE ANSWER removing ID's shows 404

-- HikaShop version -- : 3.0.0

When i enable removing ID's from product a categorie is not shown.

I have this URL: p12-inch-maxi-singles When i edit the alias of this category: 12-inch-maxi-singles (no p at the beginning) there is an problem. The link is broken.

I discover that's it a problem when a category or title starts with a number...... When i does have a number on the beginning of the URL it's is replaced with a p on the beginning of the URL.

How to fix this little glitch?

Kind regard René
