Error while Creating a new Label in the existing label file

Hi,

I am using AX 2012 R2 CU7.

I have a scenario wherein I am creating a new label. I have crossed checked the label file exists in the system and there are many labels already been used using that label file.

Now I am trying to create a new label in the same label file. However, when i am clicking on NEW button in label editor, I am getting the below error:

I have checked the label File ID lookup hold the correct label file name in which I am trying to create this new label file.

I am confused as in why I am getting this weird error.

Would appreciate for your help.

Sincerely,

Muneeb
