Hello experts

I have an issue in one of a networks in OB1 while backing up the program. 

As you can see in the attached photo, in Network6 the uploading program has an issue. 

How could it be possible?! How does the last programmer download the faulty program into the PLC? 

I want to add a FB and call it in OB1 but with this error I cant save or compile.

 Here's a couple of search results for you to go through.

Search words: end call

The other search words are from an error you get from that block

Search words: there is a stamp conflict with at least one block call

The problem you are facing is because the block was originally done in SCL and when you upload it, you can only see it in STL. All SCL is compiled to STL before uploading to the PLC.
