Problem while refreshing multiple MySql queries

I tested the graphics with several curves depending on 3 queries on MySql. Everything works fine in the builder, but when updating all the curves take the values of the first one.
My queries are identical except for a filter on the year fields. It is a comparison of the results of several years on the same graph.
Is this issue a limitation of the trial version?

To keep in mind, when you press the Run Query button, you must re-select the X and Y values.from the drop-down list.
