As per CLDR this language (gv) has only one plural form

<pluralRule count="one">n mod 10 in 1..2 or n mod 20 is 0</pluralRule>

But, in MW, we have 4 plural forms

Form 0 = n mod 20 is 0

Form 1 = n mod 10 is 1

Form 2 = n mod 10 is 2

Form 4 = everything else

This is not at all compatible with CLDR.

Suggestions:

We can inspect how the plural forms are currently used and contact linguists and native speakers to verify. Depending on the results we can consider whether we can handle these with 1=foo exceptions or whether we need to push a change to CLDR.
