Looks like some 3rd party program has added a ton of stuff.....
You can look into using DGNPurge, but offhand, those don't look like Microstation embedded cruft.
DGNPURGE check the option and any change does not arise. Thanks
Next step then is to find out what 3rd party package is adding the -mODULO OPACO etc to your files, and contact that vendor on cleanup procedures.
Can you provide a link to download the file? (or attach it here, if it is not too large) I've got some ideas of where this information is being stored.
Alexis:
It's almost impossible to say what's going on without inspecting the drawing, but some hints:
1.-Anything that have a reference can not be purged
2.-Some times text styles, line types, etc. are referenced inside a block or a nested block, or attributes of a block
3.-Nested Blocks cannot be purged if they are referenced by another block
