SOLMAN 7.2 Dashboard builder has overlapped tiles

We are at Solman 7.2 SP1. When I open Dashboard Builder, the tiles are showing overlapped and the configuration button on the tiles is not working. There is no data on the dashboard. System monitoring is already setup and the RFC MDX PARSER
is working fine and I have already followed the Thomas Paulus' blog for dashboard builder.

Please tell me how can I fix it?

Thanks,
