2 years old shot Negatives kodak trix extol 1:1 problem

Mixed fresh Xtol and 1:1 developed in a jobo.
Used Kodak rotary times as usual.
So while negatives are a little thin what is strange is the 400TX by the sprocket looks very light gray.
Just purchased a new Fuji C41 fixer and mixed 4:1. Leader test clears in less than a minute and I run it for 6-7
The Xtol smells fine and leader test show it active,
Is it washing of c41 fixer?
Is the c41 fixer taking some of the dies and making the sprocket print gray?
Any ideas?

Please show an example; I can't visualize what "the sprocket looks very light gray" means.
Also, is this on the still wet film or after drying?
