[node:language] not work when use TMGMT modules

I think SKU in ubercart must be uniqe, but when I use TMGMT modules to translate my product content from english to french, this is a bug appear:

I use uc_product_power_tools auto generate SKU, I set the token was:
sku-[node:nid][node:source:nid].[node:language]

I want to get this type after use TMGMT module:

eg:
English version product node 1 ------------------ SKU look like: sku-1.en
then node 1 translate to french by TMGMT ,the sku should change to be: sku-1.fr, but it still was same as node 1(english version) :sku-1.en

so there were 2 bug appear:
1: the [node:language] token not working when use TMGMT with token
2:there were some same SKU generated by use TMGMT module

I hope I do make clearly this bug.
