Cause
You have numbered a cable that has more than one cable target. When doing this, the "According to source and target" numbering format is selected, which outputs the device tag of the target as a counter in the device tag of the cable, e.g., -W(=ANL+EBO-X5/=ANL+EBO-H3). A conflict occurs because more than one cable target exists but only one target designation can be output.
Note:
You reach the "According to source and target" numbering setting as follows:
Select the cable in the schematic.
Select the menu items Project data > Cables > Numbering.
Click [...] next to the Settings field of the Number cables dialog.
In the Settings: Cable numbering dialog, open the Format drop-down list.
Solution
Assign only one cable target to the cable. Then number the cable anew using the "According to source and target" format.

Using a new check run (any desired scheme) this module-specific message can be deleted from the message management dialog.
