3824629 - Why I cannot find in Concur availability for the train TGV6744 leaving at 07:24

I usually always try to take the train TGV6744 Dijon-Paris of 7:24 in the morning as it is the most convenient for me. I cannot find this train in Concur.

I thought the train was always full but when checking on the SNCF website the train is available (even if written that there is no guaranteed seat because train if full, i am able to book it). 

I cannot find the TGV6744 train departing at 07:24 from Dijon to Paris in Concur Travel, even though it is available on the SNCF website. , KBA , CON-SRV-TRV-RAL , Rail , Problem
