Delete words in the description via groovy script / JWME in create transition of a cloned issue

[Deleted user]

Hello,

I need to delete some words of the description in every cloned issue.

When we clone an issue, we save the value of 2 customfields (Strings) from our orig. issue into the description of the issue which is to be created, because the 2 customfields don't exist in the new project / issue. Problem now is, the Add-On JWME also saves the "system" name of the fields, not only their values, which looks like the following:

service_2 "Value"
service_52 "Value"

Is their a possibility to hide or delete the service_xxx title of the field? Maybe with JWME or scripted postfunction in the Create transition?
