No, this would not be the reason.  It's actually
easier if there is no auto-beam setting already
defined, otherwise it would need to be cancelled
first.  But it can be tricky to get the commands'
syntax right.  Be sure you are using the manuals
for the version of LP you are using, as there have
been several changes to the auto-beam setting
commands since 2.10.  The settings you need should
be somthing like

#(override-auto-beam-setting '(end 1 8 11 8) 3 8)
#(override-auto-beam-setting '(end 1 8 11 8) 6 8)
#(override-auto-beam-setting '(end 1 8 11 8) 8 8)

to beam eighth notes as you want them

I don't think this worked in 2.10.
