VAT not included in Account move template transitory line

[BEEWAY]

Hello, I'm trying to define Recurring Moves with account_move_template addon.

I have set two lines in my move template with a transitory account 401100 :

SEQUENCE // JOURNAL // ACCOUNT // TYPE // PYTHON CODE // MOVE LINE TYPE // TAX
0 // J1 // 626000 // Computed // 1.98 // Debit //ACH-20
1 // J2 // 512000 // Computed // L(0)*1,2 //Credit //

It generates the following 2 moves in my journal :

First one is fine :
DESCRIPTION // ACCOUNT // DEBIT // CREDIT
Transitory // 401100 // 2.38 // 0
Desc1 // 512000 // 0 // 2.38

Second move is wrong :
DESCRIPTION // ACCOUNT // DEBIT // CREDIT
Transitory // 401100 // 0 // 1.98
DescTax // 512000 // 0.40 // 0
Desc2 // 626000 // 1.98 // 0

I have not the same sums in deb/cred

Thanks in advance for your help
