Some shortcodes work, but others don’t

I’m in the middle of building a website that uses Photonic. I noticed recently that a shortcode for a specific Flickr gallery will work fine, but a shortcode for a general search will not show anything.

Here are example shortcodes I’ve tried:
This shortcode works great: [photonic type=’flickr’ view=’photos’ user_id=’151210219@N03′ tag_mode=’any’ sort=’relevance’ privacy_filter=’1′ caption=’title-desc’ layout=’random’]
This was created with the shortcode generator, but it doesn’t show anything. I’m interested in searching all users for photos by a search term with this shortcode.
[photonic type=’flickr’ view=’photos’ tags=’alaska’ tag_mode=’all’ text=’alaska’ sort=’relevance’ privacy_filter=’1′ columns=’auto’ layout=’square’]

Troubleshooting I’ve tried:
I’ve deleted the plugin as well as any tables and options that I could find, and then I reinstalled the plugin and set it back up. It still doesn’t work.
I’ve looked for plugin conflicts, but I didn’t find any.
I’ve authorized it with Flickr multiple times, but it still doesn’t work.

Do you know what could be interfering with some shortcodes but not others? If you are interested in taking a look, I can share login credentials and links (they are currently behind a Coming Soon page).

Thanks in advance for any help you can give,
Pete
