Editing Bootstrap Duplicate page issue

Noticed a somewhat irritating issue when working on a Bootstrap project. If I copy an existing page and rename it and then edit this new page I notice the little star next to pages in the file menu to indicate there has been an update appears next to the original page I copied not the new page I am actually making changes to, that doesn’t have an update star at all. I have to quit Pinegrow to get it to recognise the new page.
