GA4 source/medium with sessions but no users

I am analyzing the GA4 data for a campaign on a DataStudio dashboard built for the occasion. All the data is filtered for "page path" contains "/campaign-page".

When looking at the "session source / medium" data, I noticed that several show a good number of sessions but 0 or 1 users. The affected sources / medium are mainly from UTMs, while the standard ones (like generic referrals) seem less affected.

Did you ever experience a similar situation? What could be the cause and where do you think I should start investigating?

Thanks
