How to fix this error?

Correct the entry.
The only valid characters for the hierarchy levels are the numbers from
0 to 9. The numbering of the levels starts with "1". As the levels can
only be represented with a single figure, level 10 is shown by a "0",
level 11 by a "1" and so on.
Example:
Structure: XXX-XX_XXX.X-XXX=X/XX;XXX-XX/X:XX-X/X
Levels: 1 2 3 4 5 6 7 8 9 0 1 2 3
