S1 restitued orbits not recognized

Since I try to apply restitued orbits for september files, SNAP gives an error that no valid orbit file found in POEORB folder although I copied it there. I also tried copying it in RESORB, which also does not work. Everything worked fine for august (copying both precise and restitued orbits in the same folder Snap asks). I was wondering, if there is a problem with orbit files or am I suddenly doing something wrong?
