Visual Studio Code - Intelphense vs Intellisense

I don't know if that's the case, but after I installed the extensions, I noticed that some overlapped each other in some functions. In certain functions, document formatting, for example, the VS Code requested the choice of which should be used.
This happens, in a way, between Intelephense and Intellesense, not forgetting the native extensions of VS Code.
Allow me to suggest uninstalling one of the two to see how it works, until you are able to choose the one that most closely matches your needs.
