Child Posts Permalink 404

Hi, i am using this plugin (Link) to disable base in the permalink. The plugin doing it well for main CPT Posts but when I select a post as a parent then the child permalink displays a 404 error. How to fix it?

Before using the Permalink Plugin – example.com/company/usa/google/
After Activation – example.com/usa/google/

Note – the company is a CPT Post type. The USA is parent post and Google is Child CPT Post but when trying to open example.com/usa/google/ then it shows 404 but example.com/usa/ is opening.

Please release the upgraded version of the plugin because this plugin has a lot of bugs and I’m now stuck with this because of a lot of databases otherwise i will migrate to CPT UI Plugin.
