Yes, I am aware of this problem, and I will soon fix it. This is purely a problem of the PTA; theDiagram or preset you generate with it through the buttons won't have this problem. The Omega and Wildebeest Pawns use W* as XBetza notation for their multi-push. Originally such a move would always generate e.p. rights, but at some point that apparently proved inconvenient when I wanted to use it for other pieces than Pawns, and I changed the Diagram script such that it only would generate these rights for the first piece in the table. But when you play in the PTA directly, the table is not 'cleansed' when you press Start Position, (to allow further addition of pieces not in the start position), so the Omega Pawn is not the first piece in the table.
The rule that only the first piece in the table generates e.p. rights when doing a W* move should be relaxed to the first N pieces, where N would be 1 by default, but large enough on the PTA page itself to include all Pawn types.
