display approved groups and rejected groups in notification

[AJAYKUMAR G]

One record went approval on particular state to some groups(like A,B,C and D)- in the group any one can approve
A- approved
B- approved
C-rejected
D-rejected

if any thing rejected found in the approval it went previous state
notification Sent 
"As rejected
Approved Groups
A
B
Rejected Groups
C
D
" first time it is working fine

same process
then again went approval on same state and same groups
A- Rejected
B-Approved
C- Approved
D- Approved
same notification triggered
But in notification 
approved groups both are coming(1st time apprvoed and 2 nd time apprvoed)

Rejected groups both are coming(1st time apprvoed and 2 nd time apprvoed)

I don't want that 
2 nd time what groups given that should be 
Please advise thank you.
