Fatal error when loading BN

I have a BN saved using the saveDSL function. When I then attempt to use loadDSL, I get this error:

[pyAgrum] Fatal error: condition_test2.dsl:16: 17 : error : Duplicate element NAMESTATES = (0.0, 1.0); ^ condition_test2.dsl:16: 27 : error : Too much modalities for variable BLAA NAMESTATES = (0.0, 1.0); ^ Errors : 2 Warnings : 0

I would appreaciate any help. The BN works well otherwise, I can for instance train it and create a sampler that gives realistic data.
