Hi Jatinder,
Greetings from Syncfusion.
We like to let you know that, we have deprecated the ng packages and replaced it with angular packages. Using both packages in the application may lead to installation of duplicate packages and also bundle size gets increased. We also have marked this as breaking change and documented the details regarding this in our documentation. Please find the release notes documentation in the below link.
We suggest you to migrate to angular packages instead of using ng packages. Also we request you to maintain same package version for all the components.
Please let us know if you need further assistance on this.
Regards,
John R
