Error after update

Hi,
I have updated from JEM 2.3.0 to JEM 2.3.6 version.
I had a warning message:

JInstaller: :Install: erreur SQL Duplicate column name 'unregistra_until'

Is it a problem and should I do something?

I join a screenshot with the configurations before and after update. The only difference is on the component. All the other packge seems to be unchanged after update.

Only to say, you are very late, I don't hope too late!
in addition php version is discontinued, JEM package 2.1.6 ???

Oops…
My previous update was from 2.2.3 to 2.3.0 two years ago

Now, comparing the versions numbers, between 2.3.0 and 2.3.6, I thought I had missed "only" 5 minor versions.
You tell me that It could to be a too important gap. I am feeling unsecure…
:dry:

Is there a way to check if everything is OK after my last update (and this already existing 'unregistra_until' during process)?

@McKillo: I think, you know this!

Thanks jojo12
@mcKillo, does it means that it's a "direct call" to mcKillo, and he will receive a notification from the Forum that this post need him?
Or do you suggest me to write him a (private) message?

Normally, he is getting this info. But he is very busy
