savings interest, posting wrong interest amount when savings-interest-posting-current-period-end is enable

When savings-interest-posting-current-period-end  is enable the amount of interest posted is twice the amount when savings-interest-posting-current-period-end  is disabled.

i was able to replicate this on these two accounts 

1.https://staging.openmf.org/#/viewsavingaccount/79  when  savings-interest-posting-current-period-end  is disable 

2.https://staging.openmf.org/#/viewsavingaccount/80  savings-interest-posting-current-period-end is enable.

To replicate. 

1. create a savings account with voluntary product with withdrawal fee of 300
2. opening balance 20013 activation date 1-03-2019 
3. approve and activate 1-03-2019
4. post interest on 25-03-2019
5. make a withdrawal of 19500 on 26-03-2019 
6. you will notice the interest posting total amounts to 296 on https://staging.openmf.org/#/viewsavingaccount/80  which is wrong 
7. whilst on https://staging.openmf.org/#/viewsavingaccount/79 the amount is 187 which is correct .
