For what I see, it seems a ``feature''; from lucidabr.pdf:

[p. 11]

These need undefining so that we can redeclare them.
345 \let\Box\undefined
346 \let\Diamond\undefined

...

[p. 12]

371 \DeclareMathSymbol{\Box}{\mathord}{arrows}{2}
372 \DeclareMathSymbol{\Diamond}{\mathord}{arrows}{8}

...

[p. 16]

537 \DeclareMathSymbol{\square}{\mathord}{arrows}{2}
...
540 \DeclareMathSymbol{\lozenge}{\mathord}{arrows}{8}


Best,

Axel
