Opencart Product Deletion!

Opencart 3.0.2.0 / Windows 10
Brave Version 0.65.118 Chromium: 75.0.3770.80 (Official Build) (64-bit)

When duplicating product in admin area (tick check - duplicate) - product DELETES!!! [there is NO undo from this]

Another issue is when using ‘INSPECT’ on page to check CSS etc - the highlight results are offset and very confusing.
