Many problems with the Blogger dashboard are caused by the account / profile in use.
If the wrong account or profile is in use, the simplest solution - in many cases - is simply to logout from Blogger / Google, then login using the correct Blogger / Google account. This is much less disruptive then advice to "clear cache, cookies, and sessions - then restart the browser".
The login sequence will use Google multi account login, with the well known Google "blind login" process.
Start with the "Sign out" button or link, that you see after clicking on your dashboard icon in the upper right of the screen - or the "Sign Out" link in the navbar. Click on the button or link.
That will clear the current login - similar to clearing cookies, except you only clear the Google cookies.
Now, sign in again.
Having Signed Out, you will find yourself at the Google "One account" Sign in screen. Now, you need to sign in, using the right account.
With no other problems, you should be done.
If you are able to successfully login, you should see the Blogger dashboard, with the correct complement of blogs listed in "My blogs" or "Reading List". If you do not see what you had hoped for, you can return to "Sign out", and try again.
Alternately, return to the old fall back, "clear cache, cookies, and sessions - then restart the browser" - which may be the only solution, for some problems.
