If I understand it correct, then these languages have:
3 instead of 6 WT (public edition)
and
3 instead of 12 WT (study edition)
Seems to me, the rank & file gave not enough money for translation offices/houses, so they have to reduce it. Or the 25% less Bethelites worldwide could not handle all the translation work. Or the rank & file gave not enough money to the WT and insteed of stopping the production (like India) they reduced the amount of WTs.
