Some Segments does not map properly

[kgbuddhima]

I was trying to map the properties of the following EDI model

UNA:+.? '
UNB+UNOC:3+4099200007441:14+4099200999999:14+200121:0630+ORD001++ORDERS+++EANCOM+1'

DTM+137:20200121:102'

DTM+64:20200124:102'
DTM+200:20200123:102'
RFF+CU:54321'

COM+004920899270:TE'
[email protected]:EM'
NAD+PW+4089876511113::9++Pickup Warehouse+Abholstrasse 1+Muelheim++45481+AU'
LIN+00010++40700719670720:SRV'
QTY+21:42.000'
RFF+AJL:EXW'
LIN+00020++40700719680729:SRV'

RFF+AJL:DDP'
UNS+S'
CNT+38E:10'
UNT+28+ORD001'
UNZ+1+ORD001'

Then I was testing it using a unit test and I'm having an issue where the RFF property does not map when following property is enabled.

[EdiCondition("200", Path = "DTM")]
public DTM PickupDate { get; set; }

But when I comment it and try the unit test, the RFF object will have the values as expected.

Here are the steps for the success scenario

And here is the failed scenario

Below I have added my code and I want to understand why it happens and how to fix the issue?
I was using the Nuget package before and later I have download the source code and not using the NuGet package anymore.

using indice.Edi.Serialization;
