Tablebox on temp table, additional (redundants) records

Hello, I am a Navision beginner. I am trying to use Tablebox on temptable, but it doesn’t work :/. This is what I do:

I create Tablebox, two variables: ptabletemp (temp-table buffer on purch rcpt. line) and ptablereal (real buffer on purch rcpt. line) and I add two textboxes (bases on ptabletemp) to the Tablebox.

Unfortunatelly, there is a problem: for the first time the Tablebox shows me proper data (for example 3 records), but when i press page down or scroll the mouse’s wheel, tablebox adds me another 3 (the same) records, so I have 6 which is wrong of course.

Also when I want to show no data on this tablebox (when filters give no records), it shows me one record, the lastone from the previous version of tablebox.

What’s wrong?

Yes, before populating temp-table I always reset (ptabletemp.reset) and delete (ptabletemp.deleteall).

Thank you for your help,
