Conditional relationships issue

Hello, we have an issue with uploading our data into SMRT. Let me explain the situation.

We have programmed a survey where we had conditional relationships and a number of prohibitions.
There were concepts where an attribute was missing because of prohibitions but all concepts were shown with prices. Please see below an extract from Sawtooth programming.
Participating Attributes
2, 4, 7, 8 (Agreement, Coverage, Agreement flexibility, Service Cost)
Table for Selected Relationship
Att 2    Att 4    Att 7    Att 8    Display
2              1              0                1              90
2              1              0                2             100
2              1              0                3             110
2              1              1                1              95
2              1              1                2             105
2              1              1                3             116
2              1              2                1              99
2              1              2                2             110
2              1              2                3             121
2              1              3                1              99
2              1              3                2             110
2              1              3                3             121

However, when we upload .cho file to SMRT, we don’t see concepts with null attributes. We have tried to select NA for attributes that are not relevant for certain concepts and upload data again. But still, concepts with null attributes have not been uploaded. But we need them because they had prices and we need them for analysis. Please see an extract from SMRT below.
Relationship type: Conditional Price
Attributes:
Attribute #2: Agreement
Attribute #4: Coverage
Attribute #7: Agreement flexibility
Attribute #8: Service Cost
Att 2    Att 4    Att 7    Att 8    Text to Display in Price Level
2              1              1              1                      95
2              1              1              2                     105
2              1              1              3                     116
2              1              2              1                      99
2              1              2              2                     110
2              1              2              3                     121
2              1              3              1                      99
2              1              3              2                     110
2              1              3              3                     121

Does anyone know how to upload all concepts into SMRT? Would be very grateful for assistance.

SMRT does not support conditional pricing with alternative-specific designs.  There is no way to import that table.
