The 35mm section has a comma at the end and so the comments for the anti-halation backing etc are the same as for sheet film.

The effects you're describing are probably over developerd and blown out high-lights. Foma films need careful testing to find the right exposure index and development time, they are rather prone to excessve contrast and over development if you aren't careful and need about 2/3 to 3/4 th development time of other films.
