Problem with table visualisation - columns order

Hello, I have a problem with table visualisation.

My model and data set in simplified version is:

I have three tables:

Tickets - which contain ticket number and recipient columns

Assets - which contain s/n. model and user name columns

Employees - wchich contain employee name, supervisor name

All tickets have a recipient, and all employees have supervisior, but not every s/n and model (they are always together) have user name. So visualisation should always show ticket, recipient and supervisor, and sometimes s/n and model when user (recipient) have it.

recipient name, user name and supervisor name means in fact the same so the tables are connected in that way:

(all relationships are many to many and bi directional filtering)

I made a table visualisation

P.A. and H.R. do not have any assets, but for sure have supervisor 

I do not understand why it do not shows supervisor name, even when it takes and connects right rows from all databases.

When I change the order of columns in visualisation it shows correctly...

Can you please describe me why it behave like this?

Thanks and regards!
