T.O. ECAM checklist does not recognize seat belts on

[Admiral Kirk]

Hello again,

the T.O. checks are not recognizing the activated seat belt sign. It is recognized in the checklist, but not in the ECAM T.O. checklist. T.O. check: "Unable to do!"
Checked twice on two flights in the A350-1000.

Yes, the switches are all on.

See screenshot!

It's the same issue on landing. 😉
