Variables not setting in ListView entries

I create the new entry, set its variable “Level” to 9, and add to the List View:

Put a print into the the entry class in order to check that the variable has been set up correctly:

Get this as result, the variable is never 9 or whatever, it always stays with the default value:

It can’t be any other piece of code, as it’s I’ve created a new UE Project from scratch out of desperation just in order to test this. With the 2 screenshots above and this one, you have the 100% of all the code I’ve put in the project:

Any guess why the item never gets the value set?
