Error in where-used list from & in &

What causes this issue?

An inconsistency was found in the where-used lists for &V1&.

System Response

If however, the usage was still output, it may not be correctly
displayed.

How to fix this error?

Execute program RGUSTU10 in order to regenerate the where-used lists.
Select the option 'Sets in &V2&'.
Make sure that when RGUSTU10 is being executed in this client that no
objects will be changed for which the where-used list is being
reconstructed. This could lead to new errors in the where-used list
for sets or variables.
Do not select any other options from RGUSTU10. In some cases, this may
lead to excessively long program runtimes.
If &V1& is a variable, select the corresponding option 'Variables in
&V2&' from RGUSTU10.
