After recent upgrade from SugarCRM Ent 220.127.116.11 to SugarCRM Ent 18.104.22.168, we are facing an issue on Opportunities (Applications) List view. When list view is loaded, it shows the newly created records and one existing record. As of now we see 2 new records and 1 old record so a total of 3 records are shown on Opportunities list view. When clicking "more applications", it loads one more record and the record loaded is shown in the place of all the existing records that were visible in the list view. The same behavior is shown on clicking more applications multiple times.
The List View API call only return 3 records instead on 20 records.
Please advise as to what is the reason for this issue as this a blocker for the daily work of business.
