Hi,
we have seen this behavior if the campaigns to which they’re linking were not imported to the SAME directory path as they were on the source system.
If the structure has changed, like including case sensitivity of the folders or permissions of the folder structure, then the target link cells would effectively not exist on the target. The finding of those cells is path based.
What you can try is import the LINK node and linkable CELL node campaigns separately.
Thanks,
Beate
