there is a problem with indicating Z/E isomers in SMILES generated from mol2 files.
Eg. for 1,2-dichloroethane. For structures saved in mol files, smiles (smi or can) are generated correctly:
babel Z.mol -o can
Cl/C=C\Cl Z
1 molecule converted
32 audit log messagesbabel E.mol -o can
Cl/C=C/Cl E
1 molecule converted
32 audit log messages
while for files saved in mol2 format, we dont get the E/Z isomerism:
babel Z.mol2 -o can
ClC=CCl Z
1 molecule converted
32 audit log messagesbabel E.mol2 -o can
ClC=CCl E
1 molecule converted
32 audit log messages
Converting mol2 back to mol fixes the problem.

Can you provide a test file?
E isomer
Z isomer
Here they are. Files generated in ChemSketch 12 v. 12.01 and exported as mol2000.
This bug refers to MOL2 files, but the examples you provided are MOL files. Which is the problem?
