This is caused by a bug in the mm macro package.
Figure titles are printed with address@hidden which defers it to
either address@hidden or address@hidden depending on whether it
appears between a DS/DE pair.
Unfortunately, the condition is wrong.
Change line 2548 (v1.19 - don't know if this is different with another version)
    .ie \\n[ds*lvl]<1&\\n[df*float]=0 \{\
into
    .ie (\\n[ds*lvl]<1)&(\\n[df*float]=0) \{\


Hope this helps,
