Empty Meta Tags

I've got some empty meta tags that look like this:

Which is odd since the code looks like this:

...so the content is filled in, saved, but nothing is showing when rendered on the page. What am I missing?

This is on Perch Runway 2.8.9 FYI.

I know it's an old version. This was working for a long while and stopped recently. Nothing has changed on our end though.

Thanks Hussein - but my sample code shows that I'm already doing that - the closing tags are there.

Ah - wrong place! Fixed, works. Thanks! Staring at the string too much, I didn't even see that.
