How to fix updated footer of OceanWP theme?

Hello guys,
I’m using OceanWP theme (free version) installed in several worbsites, using elementor as an editor plugin, very familiar with updating every section of the theme,
but recently I noticed that two websites I’m managing, updating them, the footer section turned to be dark gery as the default theme, I tried to update it (background color) fonts style, size, bottom dimension, as I used to do and still doing in the other sites, just be saved and display during the settings, but when out from the customizer page setting it turns to the previous default dark grey background, default fonts, etc
I don’t understand why this issue happening, and just with 2 website sites, but the other websites are still fine to save the manual settings,

I’m thinking to delete and erase the whole website from the cPanel, but that will come on the cost of starting from scratch,
Any idea or recommendation on how to fix this issue??
Please advise, with many thanks in advance,
Regards,
