Portal showing next record outside its area

[Skasie]

I have several portals arranged in a horizontal way (same relation). Each should show only one row and the first record to show is set to 1, 2, 3,... . On a Mac the result is a horizontal portal showing me all the records 1, 2, 3,... of the given relation.

On windows I always get an additional record showing outside the portal bounds. In the first portal I get record 1 and record 2 as a "ghost". In the second portal I see record 2 (and 3 as "ghost"),…

Is this a known bug of FM 8v2? This makes my application useless on a PC (and I tried different machines)

Maybe someone can direct me to a solution?

Thanks,

Martin
