Screen shot of LO portable showing the minimized value of 0,20 sec.

For an automatic foil change during a slideshow I have set the time to 20 seconds. LO, however, ignores the setting and change the foil after hardly 2 seconds. Increasing the value to 120 seconds does not change the behaviour.
Hence I installed LO Portable in the version 4.1.5.
The value of 20 seconds suddenly changed to 0,20 seconds! This means a factor of 100 lower then set. I changed to 20 seconds and it worked perfectly. 
Last test: I changed the setting to 12 seconds for all foils in LO portable, stored the file, closed the portable version and started 4.2.2.1.
Now the displayed value became 1200 seconds! (factor 100)
But, at least, the time between a foil change is the set 12 seconds.
