Deb:
EA 50 has an important  proportion of Light Green (this is  even more
dangerous if fast green FCF is employed instead of light green),so the ratio
light green/eosin+bismark brown is high. EA 65 has a more rational
composition, including  half of the amount of light green and giving then a
more precise coloration.
Try the other batch but it looks like there is an irrational formulation of
the
stain.
