Windows 10 Hugo v0.19 Live Reload only after second shot


I am just starting with Hugo on my computer. Did load the hugo-creative-theme and do customize it (edit the config.toml file). Hugo server runs and automatically refreshes my browser view, but most times the changes are not reflectet. I need a second refresh of the browser to see the changes. Tested with Chrome and Edge. Any recommendations?

Thank you
