4814	DAE genereated by the NF leads to unbalanced systems in the backend	Francesco Casella	Per Östlund	"Please check [https://libraries.openmodelica.org/branches/newInst/Modelica_3.2.2/files/Modelica_3.2.2_Modelica.Blocks.Examples.Filter.err Modelica.Blocks.Examples.Filter ]. After creating the DAE data structure, 34 variables and equations are reported. However, pre-optimization reports 36 equations, and matching fails reporting 36 equations and 30 variables.

The problem affects other models, such as [https://libraries.openmodelica.org/branches/newInst/Modelica_3.2.2/files/Modelica_3.2.2_Modelica.Blocks.Examples.FilterWithDifferentiation.err Modelica.Blocks.Examples.FilterWithDifferentiation]"	defect	closed	high	2.0.0	New Instantiation		duplicate
