How can I solve this visual glitch in my JavaFX TableView?

Question

Left column: checkboxes to select or deselect the rows selected by default. Right column: A line representing the number of selected lines before the line and including it. Therefore, deselecting a check box in a row changes the values ​​in the rows below.

Error: Scroll down to the bottom of the table. Uncheck the box with invitation code 74. Select it again. The last three invitation codes should read 73, 74, and 75 again. But quite often they show 73, 73, 74 or 73, 74, 74.

The error does not always happen! If this does not happen, scrolling up and down with the scroll bar of the table and repeating the above procedure can lead to its occurrence.

It seems that the error is only visual - I made it dump the contents of the ObservableList to the console and display the correct values. Besides this visual glitch, my application is working correctly. Clicking on any other control in the window (for example, the scroll bar of a table) flips the invitation codes in the table to the correct value. Going to another workspace on my desktop and going back also shows the correct values.

A small image showing the console dump of the ObservableList on the left, the listening table on the right.

The question is quite logical: How can I crush this error !?

EDIT : Threw away more code, as Kleopatra advised. Thank!
