Checking the GetRewardPointAdvancedCalculateTable and the SetRewardPointAdvancedCalculateTableFunction , something is wrong here

If I choose the ot_shipping I guess it's related to the ot_total (?) , since when I click update ( with subtract) , it add the ot_total (but with the action add ) ....

But as you can see in the SetRewardPointAdvancedCalculateTableFunction it's setting a t_total.php .... maybe this is the issue ?
But related to what ? jscript ?
Still didn't find out

GetRewardPointAdvancedCalculateTable
Array
(
[0] => ot_total.php
)

SetRewardPointAdvancedCalculateTableFunction
Array
(
[0] => Array
(
[module] => t_total.php
[action] => Add
)

)
