Some columns of SysImage are not available for data binding

Dear Community,

Happy New Year ! 

I noticed a strange problem on cloud environment with 7.17.0 version.

When i'm trying to bind SysImage data to my package i can't choose the columns

"Data" and "PreviewDate".

Here is the list of available columns:

I tried to do the same on Demo Marketing Environment with 7.17.1 

and i haven't seen this problem, the columns were available for data binding.

I checked that Columns "Data" and "PreviewData" have Usage mode = General in SysImage object. 

Do you know what might be the root cause of this problem?

Thank you in advance,

Anna
