@Ronnie09 Which core component are you refereing to? can you also provide screenshots?

@HeenaMadan There was no error in logs as well actually.

@arunpatidar No there was no console errors.

@akshaybhujbale auto-created properties (such as jcr:primaryType) are not subject to an overlay/override to ensure that the node type currently under /libs is respected. It may mean that it is created and administered by the system and can only be read (but not changed or deleted).

@Lakshmi9 Can you attach the screenshot of the overlay structure from crx?

@Lakshmi9 Please check if the core pakages are matching between environments. you can check this in package manager -  core.wcm.components.content-x.x.x.zip
