When I copy and paste within the same document, the styles formatting changes. I noticed this only happened after I changed the names of the styles. I had an older original document that maintained the styles when I copy and pasted, but once I did this new save-as document and renamed the styles, they no longer stay so that I have to click on the style again up in the gallery box to fix it, which defeats the purpose of doing a copy and paste. This is not numbered formatting, just basic font changes, like bold and size changes. When I copy and paste, it reverts to a blue Calibri Light font, the kind that looks like it's default with Word. It retains the bold and font size, but the color and font name changes. The box to change automatically is NOT checked.





Also, this is Microsoft 365, but it didn't have an option to choose this.
