Hello, Techgaon,
We fixed spaces for this element on your web-site and the fix will be globally added in next theme update.
You may also configure settings of this element to get another visual result because you have many product categories and many of them have children of another one and another one.
Examples:

3/ https://prnt.sc/V6gO-zgg1eF6
4/ https://prnt.sc/UyruWKFwyCJS
If the expected result cannot be reached, please, provide us with more details of the appropriate result and we will try to help you with getting it ready.
Kind Regards,
