ketcher generate wrong *.ket format while processing reactants and catalysts

[Pandaaaa906]

wrong number of reactants and catalysts
.ket file from ketcher 2.5
python indigo 1.83

from indigo import Indigo

indigo_ins = Indigo()

r = indigo_ins.loadReactionFromFile(r"D:\reaction.ket")
reactants = r.iterateReactants()

for reactant in reactants:
    print(reactant.smiles())
if __name__ == '__main__':
    pass

Output:

C1CCCCCCC1
CC(=O)[O-]
[Na+]

Expected:

C1CCCCCCC1
CC(=O)[O-].[Na+]
