Here is what I did.

Login >>

'My settings' tab >>

Find 'Enable/Disable the ability to lock/unlock your domains' under 'security settings' and click 'view' >>

Make sure 'manage securelock' is selected in first dropdown menu>>

Make sure 'Enable domain locking for this account' is selected in second dropdown menu >>

Click 'Update' >>

Click on 'manage domains' tab >>

Here is the tricky part......
Click the link to the domain you want to edit/transfer
(instead of using the checkboxes and clicking modify)
Do this for each domain individually...

Check 'domain status' to see if the domain is locked or unlocked... if unlocked goto next step. If locked then click the 'locked' link >> and unlock the domain >>

Click the '+' to open the 'domain contact information' box >>

Click 'Configure' >>

Use this time to edit any info that might need updated as this may slow down the transfer...
Auth code should be there, and shouldn't change regardless of whether you edit/save your contact details.

Hope this helps. It worked for me.
