Cannot transmit 2024 T3 tax slips

I attempted to transmit a 2024 T3 summary and tax slips to CRA using Taxcycle T3 program but failed. I attempted to transmit once gain as the screen still show a message that “Ready to transmit”, however, the number as shown on the “Original slip”, “Amended slip” and “Cancel slip” are all changed to zero. There is no response after I hit the “Ready to Transmit” bottom.

Can anyone please tell me how to transmit the 2024 T3 slip, thanks
