Issue with FX assign not stored between session

Hello,

Rekordbox 5.7.0 / MacOS 10.12.16 / MacBook Air7,2

I have an issue with the FX panel, each time I launch Rekordbox the routing is reset to FX1 channel 1 and FX2 channel 2.

I switch them both to Master but on the next session, they have reset their condition.

Thank you.
