Asset Export Password bug

If I export artboards to pdf using the asset export window - each file will be password protected without me specifying it.

This only happens if the last pdf I saved manualy (using save as) was password protected. Asset export will use the same password that I entered for this file.

This would be a nice feature if it was an option you could select or de select, but not when it happens without informing me.

The only workaround I know of, is to save a dummy pdf with the correct settings before using the asset export, needles to say this is a damper on workflow efficency.
