Belos online Doxygen documentation has two pages for Belos::BlockCGSolMgr
Apparently, both of these pages are generated from BelosBlockCGSolMgr.hpp, but one is rather sparse in documentation (i.e, https://docs.trilinos.org/dev/packages/belos/doc/html/classBelos_1_1BlockCGSolMgr.html), while the other appears more complete (i.e., https://docs.trilinos.org/dev/packages/belos/doc/html/classBelos_1_1BlockCGSolMgr_3_01ScalarType_00_01MV_00_01OP_00_01true_01_4.html).
It's not clear to me why this is, but it's confusing.

I'm guessing this might have to do with the fact that the latter is specialized for lapackSupportsScalarType=true.
There's also a rendering error in that page.
