The problem is your 3dcalc command. There are many sub-bricks in each of the 3dDeconvolve/3dREMLfit output, but you only need to focus on one specific sub-brick for your group analysis. So specify the sub-brick by finding its label or index number, and then insert it in your 3dcalc command, something like:
3dcalc -a stats.xxxxxxx_20140102.mid2_REML+tlrc'[#ConditionOfInterest]' \
-b stats.xxxxxxx_20140109.mid2_REML+tlrc'[#ConditionOfInterest] \
-expr 'abs(a-b)' -prefix xxxxxxx_absMid2
