The limit of 255 characters for paths & titles is too small for combinations of some tokens.
For example the following paths setting cannot be saved:

articles
articles/[node:field-category-primary:parent:parent:name]
articles/[node:field-category-primary:parent:parent:name]/[node:field-category-primary:parent:name]
articles/[node:field-category-primary:parent:parent:name]/[node:field-category-primary:parent:name]/[node:field-category-primary:name]
