The Tross components put to gether should be 150,30 and 30 cm.

No one have an idea?

you have worked on the children without referencing the parent, explode the parent then select the two orphans, make them a component, new parent should match, however there is slight difference due to position differences between the two children

thanks! i exploded and made a new component, then it seems to be ok again.
