[Help Needed ]for hacked website and data-vocabulary.org schema deprecated

Hi, I desperately need help for my website and thanks in advance.

1. changed the theme after being hacked
2. after changed the theme, I used "site: my site" to see the indexed pages. but found heaps of hacked titles and descriptions even my homepage shown as below, but my IT support checked these pages, found no trace of hacked pages. When I open this pages, they turned out to be my normal pages.



3. I submitted url to google search console, and found unnamed item indicating data-vocabulary.org schema deprecated. Very strange, as my website is a informative website, no product is selling, I do not understand why this happened and how to fix it.



4. my IT support suggested to wait for a while and see if they will automatically gone. I am not sure it is a smart move and welcome your advise. I checked some reference, some people said it may be because of the theme outdated and not changed to Schema.org

I have experienced such things before, and it took some time ( about a month ) for the errors automatically disappearing.
But also, I think there is not a specific problem to solve those problems.

thank you so much for your reply. Now the good news is I do not need to do anything, the bad news is I have to wait for one month to get the result.
