For old versions, I have solved this problem by disabling uppercase from css files
.sidebox-title span, .sidebox-title a { color: #fff; text-decoration: none; /* text-transform: uppercase; */ font-weight: bold; font-size: 90%;
This problem looks css based.

This is not solving, this is escaping. I want UPPERCASE but with true way.
