How can I fix the recent change in the appearance of the info panels?

[Valentina Ochoa Arellano]

Since last week, the info panels have been changing their appearance when the page is updated. Although they look the same as always when inserted into a Confluence page, when the page is updated, their color changes and the icon/emoji disappears. I've noticed that only the default info panels retain their original appearance; if I make any changes to the icon or color, the appearance changes. Does anyone know if this is a bug or a recent change? I’ve asked Rovo about it several times, but I haven’t received any helpful answers. I'm attaching screenshots to illustrate what I mean.

Not a solution to the actual problem, but at least a workaround that worked for me: Before you update the page, you can click on the menu on the left-hand side of the panel and select "Sync block".
For whichever reason this prevents the panel to change the the legacy one.

I've had maybe similar color/shading issues, and posted here https://community.atlassian.com/forums/Confluence-questions/Color-shading-different-between-edit-mode-and-not-edit-mode/qaq-p/3270917?utm_source=atlcomm&utm_medium=email&utm_campaign=immediate_general_answer&utm_content=topic
