Copy/paste text graphic also copies the markers

Hi

I am a long time Premiere user and have an odd problem I cannot solve.

I create text using Essential Graphics. I have a graphic with text in it set up in a certain way. Save redoing that everytime for the whole film, I highlight the clip, copy and paste (or alt-drag) and change the text to suit. Fine. However I often use markers on the text graphics to highlight various words so I can line up visuals, however, when I copy/paste a text graphic clip it also copies the markers and if i then delete or add new ones it also shows them on the previous clip (that I copied from) - so the graphics are unique/independent in terms of text but NOT unique for markers. I cannot seem to make the clips 100% unique in terms of markers (which means I need to start a new text graphic for each super/subtitle)

I am on v23.6.8 (still on an older version due to long running projects) however I am sure it didnt used to do this...

Any ideas how I copy a graphic and make the markers unique/independent to that clip?

Thanks
