I think this is just normal behavior with classes. But since you haven't shown any code, I can't tell exactly what you're doing and what you're expecting.

When providing bug reports, you need to provide:
- Exactly what code you're executing.
- Exactly what output you're seeing.
- What you expect if it's different from what you're seeing.

Please provide this in the body of a message as text, not (for example) as an attached image file.

Thanks.
