Text fitting for bullet points - how to retain adjusted formatting?

I’m wondering if there’s a way to keep the “text fitting” formatting—that have been set by me—from changing back to their default setting when new text is copied in?

For example, in a bulleted list, I’ve set the indentation to X and the hanging indentation to Y. However, whenever I paste in new text, it moves both the indentations back to the original / default settings (to 0.25 and 0.25 — which seem to be default.)

I’ve tried using “paste without formatting” in these instances, which doesn’t seem to work. Does anyone have insight into whether there’s a way to keep this particular formatting from changing?
