Can't add Primary Key and Auto Increment field to table

[Sandy]

I may have found a problem adding primary key fields -

I had a simple table with a few fields, no keys, no auto increment fields (definition below). I opened the table from the explorer, and went into the `column` tab to add a new field `id`, checked the key column and it checked auto increment and not null.

Saved the updates, get a message that 0 is a duplicate key. Column gets added and all are set to 0.

Something seems broken here as I'm pretty sure I could add a primary key after the fact.

Running 7.4.201 / Windows 10 Home
Db version - 10.0.34-MariaDB-0ubuntu0.16.04.1 on a Ubuntu Linux box
