Solarwinds NCM issues

We have noticed an issue with NCM where it is only saving half the config output from switches on a certain version. The problem seems to be because the session prompt appears in the config.

Example:

Switch name= Switch1
Switch session prompt = Switch1#

Line in config to specify this = session prompt default "Switch1#"

It appears that NCM sees the session prompt within the config output and thinks this is the end of the config therefore doesn't save anything after this. Problem is this line is about halfway through the config. I can't work out why it is having this problem though as older versions of these switches have the exact same session prompt line in the config and it seems NCM is ok backing these up and doesn't cut off the end of the config.

Anyone had this issue before? I feel like every time I try and configure 1 thing on our Solarwinds I run into 10 other issues stopping it from working properly.
