3dMEMA error

Dear afni experts,
3dMEMA execution halts after the following lines:

Have lop$centerType 1
Have lop$centerType2 0
Have lop$centerVal[jj] 25
Have lop$centerVal[jj] 26
Error in cbind(lop$xMat, lop$covData) :
number of rows of matrices must match (see arg 2)
Calls: process.MEMA.opts → as.matrix → cbind
Execution halted

kindly help me figure what am i doing wrong here?

My covariate table looks some thing like this: (There are 98 subjects in total)
subj Age Edu
042 24 17
044 27 16
079 24 25

The 3dMEMA script looks something like this:

3dMEMA -prefix $results_dir/P-H
-mask $mask_dset
-groups HC PT
-covariates /mnt/e/MROT_CLEANED/Covar_MEMA_FIXED.txt
-covariates_center cov1 = 25 26 cov2 = 16 15 -covariates_model
center=different slope=same
-set HC
