Bug Report: Generative Dialog Box Not Working with "Add" and "Subtract" Buttons

The generative dialog box in the beta ver. is not functioning correctly when the "Add" and "Subtract" buttons are clicked. The expected behavior is for the dialog box to generate prompts based on the selected operation, but it fails to do so.

"Add" and "Subtract" buttons also not working in pic which I uploaded but it works on templates

the problem is in Chrom Browser
