osl_example_beamforming error: Item plugin: No field(s) named montage_osl

[Hpsy]

Dear OHBA Group,
Using demo data, I run the osl_example_beamforming.m (line 215: D_epoched = osl_inverse_model(D_epoched,mni_coords,S); the error information displayed as follows:

Initialising batch system... done.
Item plugin: No field(s) named
montage_osl
Item plugin: No field(s) named
spmeeg_osl
Error using spm_jobman>fill_run_job (line 472)
No executable modules, but still unresolved dependencies or incomplete module inputs.

Error in spm_jobman (line 247)
sts = fill_run_job('run', cjob, varargin{3:end});

Error in osl_inverse_model (line 244)
spm_jobman('run',matlabbatch)

Any help with regards to figuring this out would be greatly appreciated.
Thank you in advance,
Li
