Issue with Mirroring a Feature in Creo: Original Feature Disappears

I'm currently facing a peculiar issue in Creo and could use some advice. I've created a part with a specific feature - a hole cut out. The problem arises when I attempt to mirror this feature. While the mirroring process itself seems successful, the original hole cut out disappears.

Has anyone encountered this issue before? What could be causing the original feature to vanish upon mirroring, and more importantly, how can it be resolved? Any insights or solutions would be greatly appreciated.

Thank you in advance for your help!
