Withdrawing learners after offering date has passed

Summary

Unable to withdraw learners after the offering date has passed

Hi

I have an issue with withdrawing learners once the offering date has passed. Sometimes it works, but more often we get the following error message: 

 

The selected learner was not withdrawn from the learning assignment (WLF-5145154)

 

Any ideas what we are doing wrong?

 

Many thanks

Sarah
