I think you’ve shared a link to your collection, but with the boxes for “count hidden troops” and “count unobtained troops” both ticket. The link just shows all troops in the game - obviously not your collection.
If you scroll down below the resources on the right hand side of the page, you can find and untick the two boxes, then using the “tools” option at top of the page (under “collection”), you can share your collection as a web page. Try that and hopefully we should be able to see the troops you have
