Duplicate images on Pro version of Instagram Feed

My instagram feed has started showing duplicate images. It’s not consistent, but depends on the numbers I use, and whether I refresh the page.

Here’s a sample of the code I’m using:
[instagram-feed includewords=”#wyoming” num=12 cols=3]

When I first set this up, it looked great! But when I refresh the page, the problem occurs. Now this will show picture A 2 times, then picture B 2 times, then picture C 2 times, etc. If I change the parameters to a different num & cols, then I can get it to go back to correct single display of each photo. But then when I refresh the page, they turn back to duplicates.

When I changed it to num=6 (there were 7 photos altogether), then it showed just the first 6 correctly. But in this case, when I did a “Load more”, the next 6 that showed up were exactly the same as the first 6.

The first time I’ve seen this problem is today. I’m using the Instagram Feed extensively on my site, which is why I purchased the Pro version, so this is a significant problem.

I hope you can help! Thanks! – Deanna.
