Incorrect Data showing on SQ327 / SQ328

The data showing for SQ328 from Singapore to Manchester via Munich and SQ327 to Singapore via Munich is showing incorrectly.

SQ328 seems to have been incorrect from the 31st March - showing flights as cancelled that weren’t and incorrect times for the other flights.

SQ327 is regularly missing the Manchester to Munich leg and from the 31st March is showing incorrect data for the Munich to Singapore leg - incorrect times and flights showing as cancelled that weren’t.

Is it possible to rectify this?

Thanks
