Unable to delete input parameter if reusable component is called in a higher component

Issue: 

If an input parameter is created in a reusable component and this component is called within a higher-level component, the input parameter becomes static and cannot be deleted. 

If source A has a reusable component with four input parameters and source B has the same reusable component but with three input parameters, importing the reusable component from source A to source B will result in an error. Reusable components with differing input parameters cannot be imported between sources. 

Solution: 

Create an additional input parameter in the source file and then try importing. It’ll be successful. 

You can also change the parent folder of the reusable component by moving it to a different folder that has fewer input parameters. This way, the reusable component will be considered a different one and can be imported successfully.
