ERP in excerpt

hi,
I get problem with the plugin. the setting is
Do Not Auto Insert Into Posts
as I insert it manually in template.

However when I use get_the_excerpt(), I get the ERP content at the beginning of it. How can I get rid of this, as I need it only in the content and also just as specified in the template (this works ok).
