There's a good chance the data is outdated (in my experience those reports aren't updated very frequently, especially if the URLs aren't regularly crawled). I can't see any noindex directive via my browser (server-side HTML, rendered HTML, or HTTP headers) so this is probably the case assuming your website isn't serving differently depending on user-agent/IP.

As Tony suggested, try inspecting an example URL in GSC and see if it reports the noindex in a live test. If not, validating the issue in GSC should "fix" it although it might take some time for all of them to be re-crawled and indexed.

Failing that, you'll probably have better luck with asking the GSC Help Community. try it GSC Help Community
