I rarely use quick edit but I noticed there was a bug in it and I'm reporting it. If the quick edit doesn't work then there's something wrong. Saying, "just don't use it" is not a fix. But it seems you had nothing to add except to say that the title, that was imported directly from aliexpress and unedited, was too long...
Bugs may have a bigger underlaying cause and I'm worried this may be linked to something more serious than just not being able to edit the correct item as it is clearly pulling data from a different post id (even after deleting all products an re-installing the plugin).
I will definitely contact support but I think it's better to ask the community first, most times the answers we get here are useful.
