Reset layouts numbering

Hi all,

when I PDF-print the parts of my score the numbering is quite mixed up.

01 Trumpet 1
02 Flute 2
etc.

(This score came from an xml-import, maybe thats why.)

I find, that in setup>layouts the numbering is also in this weired order.

=> is there a command to reset the numbering to the score order?

In setup mode, “Renumber Layouts”
