problems by selecting a row in a table

Very good morning,

we have a table created with a z-bol. When editing the table with a button, not 'running selection fine.

But it works ok when we add a row, or when we delete a row.
The second image shows that selected by the mouse click row is the third row, but turns blue the first row, and that gives us problems.

Step 1. before to edit mode

Step 2.Edit mode. I select a row

thank you very much
