I checked and found that decrypt check mark is active in HTTPS tab (by default).
by real target I mean, for example, there is a page getting a value and sends it and shows the response (result) in the browser, Fiddler doesn't show the target URL. like using online SEO tools.
I asked the developers and realized they use APIs but Fiddler doesn't show the URL of the target site.
I hope this makes it clear.
