Hi, Antonino.

Yes, i am able to reproduce this with the latest version on our Sandbox Demo site, as well.

It does duplicate some table settings and the main data,

but things such as adding a custom CSS Class in Column Display settings, and Custom Column Width values,

that does not copy to the duplicate tables.

We have sent this to our QA Team, they will check it out and compare the behaviour with the older version to confirm if we officially have a bug, it does seem so.

As soon as we confirm this, we will report back right away.

Thank you for your patience.

Hi, Antonino.

Thank you for confirming that it works for you with the previous version without issues.

Our QA is still testing everything to confirm the bug.

We will report back when the testing is complete, and I will advise you when we add a task for our developers to work on a fix.

Thank you for your patience.

Hi, Antonino.

It seems our QA Team has found a bug with our latest version for duplicating Tables.

For the time being, you can use the older version until we fix this,

if this functionality is crucial for you.

Our developers isolated the bug, and they'll add it to their queue for fixing.

 They will do their best to build a fix as soon as possible.

 We don't have an ETA on when the fix will be available, but please keep a lookout on our wpDataTables changeLog.

It will be stated there during updates which bug fixes have been implemented at each update.

Sorry for this inconvenience.

Hi, Antonino.

Just an additional follow up.

Our developers isolated the root of this bug,

and they made a fix - we just need to conduct more testing before it is added to the plugin's core.

We are confident that this should be fixed in our next Update, so when you see the next update offered,

please do so and this should be fixed after that.

For now, you can use the older version, before we roll out the fixed version.

We will be here if you have any questions.

Thank you.
