Hi there and welcome back to the forums! Sorry you’re hitting some trouble here, but hopefully we can figure it out here together. 🙂
That’s certainly an interesting issue! Â We’ve had reported issues with duplicated events importing but not specifically with multiple images in the Media Library.
I was unable to recreate the issue on my setup using the default WordPress Twenty Fourteen theme and no other plugins. That makes me wonder if there is conflict at play with your theme or one of installed plugins.
Could you try temporarily activating the default Twenty Fourteen theme, to see if the issue happens there as well?
If disabling the theme fixes it, that’s good news! It means we have narrowed the issue down to a theme conflict.
If the issue is still there when using the default Twenty Fourteen theme, then we can try testing for conflicts with other installed plugins. Using the Twenty Fourteen, please try deactivating all of your plugins, except for the ones from Modern Tribe. Does that solve the problem? If so, reactivate the plugins one at a time until the issue pops back up, then tell me which one was causing the issue.
These steps are also outlined here if you want some more details on how to test for conflicts.
Give those steps a shot and let me know what you find.
Cheers!
Geoff
