Journal entry from salary slip not deducting loans

hello community .
I am using the loans system , still testing it . so everything seems to be working fine until the creation of the salary slip. as you can see the total paymet is 13500, loan deduction is 1000 so net pay is 12500. so I should get a 12500 journal entry . because the 1000 already transferred to the employee at the beginning . can anyone explain this behaviour please ?

Good day,

Were you able to solve this issue?

I have the same challenge.

No entry on the journal to reduce loan balance in the loan account
