Recent contacts work inconsistently

The recent contacts do not add the address sometimes. This is issue was reported to me and i opened a PMR after a long time fighting against this issue.
IBM reproduced the problem and open a SPR

Steps to reproduce the issue:
1- Make sure your File / Preferences /Contacts are set with the option
below:

“Choose how names are added to Recent Contacts”

select “Add the following names”
select “All names”

2- Install the Notes client Notes 8.5.3 FP2 Standard or follow the
procedure from TN below if you have the Notes 8.5.3FP2 installed:

http://www.ibm.com/support/docview.wss?uid=swg21265985

3- Open the Notes client, open the contacts and select the view Recent
Contacts

4- Selected all contacts and delete.

5- Close the contacts.

6- Create new message, type any address and send it.

7- Restart the Notes client.

8- Create new message with any other address and send it.

9- Open the contacts and select the view Recent Contacts

- as you can see the last address was not added to the Recent Contacts,
you can only see the address from the first message.

- the parameter below does not affect this issue. I waited about 10
minutes but the last contact was not added. If you restart the Notes client
the last address will not be added.

DPAB_PROMOTE_INC=1 (set to refresh every 1 minute)

This was reproduced on Notes 8.5.3FP2 Standard Brazilian Portuguese and English version

Workaround:
- The last address will not be added to the recent contacts until the user
sends any message or if he tries to create a new message and type part of address
and click on the F9 key (name lookup algorithm) and select any address
from the list.
