No worries mate :-)

Much appreciated!

Thank you so much

Thank you a lot.
I have ignored for other posts.

Will this not affect my sites's ranking or something for my posts?

Not at all. They show up on some of my posts which still rank up quite high.

Wow thank you so much for this

Oh ok coolThank you a lot. I have been removing it indeed because I was scared it was going to affect ranking.

It will only affect the page you have it on. Google will probably not indexed that page. It doesn’t affect your whole website unless it’s on every page.
It really depends on how Google define’s the error.

Here is a troubleshooting guide from search console. I can’t post the link because it won’t let me but I can copy and paste some information.

Troubleshooting
Here is a basic process for prioritizing and fixing rich result issues on your site:

On the summary page of a rich result report, filter out the warnings and valid items and focus on the errors first.
Fix errors according to the number of affected pages:
If there is a spike in the error chart, look for a corresponding spike in the error rows in the table.

Fix the issue on your site, test your fix, and ensure that your fixes are live on the web. See Inspecting errors to learn about the different tools to view and troubleshoot your structured data items.
Return to the issue details page and click the Validate Fix button to begin the validation process. This process can take several days, and you will receive email notifications of the progress.
If all instances of that issue are found to be fixed (that is, the fix is validated), the count of pages affected by that issue will become 0 and the issue status will be updated.
Continue fixing errors.
When all errors have been fixed, remove the filter for warnings, and consider fixing the warnings. Most warnings are about missing optional properties in your structured data. Having more information in rich result can be more useful to your site visitors.
