However, the Open for Edit assets should have been REVERTED (Ctrl+R), and NOT committed. What I want you to do is follow these steps EXACTLY AS WRITTEN.
1) In the Search box, add the filter Asset KUID:<kuid2:394799:100085:11>. Click Apply.
2) Right-click on the only result and choose "Show Dependencies".
3) Click "View in Main List".
4) In the Search box, add the filter Locally Modified:True. Do NOT touch the Asset KUID filter, even if it appears to be blank. Click Apply.
5) Select every asset in the list and press Ctrl+O.
6) If there are assets that do NOT revert, delete them.
7) Change the "Locally Modified" filter in the Search box to Location

ownload Station. Click Apply.
8) Download everything. Wait for the download to complete.
9) Remove the "Location" filter in the Search box. Click Apply.
10) Select all the assets, right-click, and choose "Show Dependencies". If it warns you that it will take a long time, click "OK".
11) Return to step 3 and repeat until you get down to a small set of assets where you can see for yourself the presence or absence of the Green Triangle indicator.
If you need any clarification, don't hesitate to ask.
