Tag Page Title Not Displaying Properly

Hi,
I am a new Rank Math user. Migrated from All in One SEO on my iphonetricks.org website. However, I just noticed that the tag pages have an empty title in the browser and also in the meta tag:
<!– Search Engine Optimization by Rank Math – https://s.rankmath.com/home –>
<title>| iPhoneTricks.org</title>
<meta name=”robots” content=”follow, noindex”/>
<meta property=”og:locale” content=”en_US”>
<meta property=”og:type” content=”object”>
<meta property=”og:title” content=”| iPhoneTricks.org”>
<meta property=”og:url” content=”https://www.iphonetricks.org/tag/wwdc-2020/”&gt;
<meta property=”og:site_name” content=”iPhone Tricks”>
<meta name=”twitter:card” content=”summary_large_image”>
<meta name=”twitter:title” content=”| iPhoneTricks.org”>
<meta name=”twitter:site” content=”@iTricks_org”>
<!– /Rank Math WordPress SEO plugin –>

Any idea why this happens and how can I fix it?

I checked the Rank Math Settings -> Titles & Meta -> Tag Archive Titles are set to %tag% | iPhoneTricks.org

Thanks for your time.
