Hello @alanik7725 and welcome to the forum 
could you share your graph or at least an image…its really hard to help with only these information
yes sure
I cant upload file can you give me a email address ?
No not really ;)…try share at webtrnsfer,whatever and share the link here

allright cheers…these costum nodes you use seems to be very old…guess that package havent been upgraded for years probably they have a github where you could create an issue…and be lucky if they can answer
