CA PPM Advance Reporting Theme is set incorrect after Jaspersoft content migration from Jaspersoft 5.6.1/6.1 to 6.2.1

We upgraded from Jaspersoft 5.6.1/6.1 to 6.2.1 and under Advance Reporting we see some functionalities like schedule button doesn;t appear. 

Steps to Reproduce

1. Upgrade PPM from 14.2 to 14.xx or 15.x

2. Migrate Jaspersoft content from Jaspersoft 5.6.1/6.1 or 6.2.1 

This is a known bug DE33811 and resolved in 15.3
