How do I reset General Preferences in Premier Elements 12?

Question

Having used Premiere Elements 10 for a while, I now have Premiere Elements 12 on my PC, I like to set the duration for still images to 5 secs, not the default 6.  I made a mistake when doing this by altering the Video Transition Default Duration in error, realised my mistake and reset that at 30 frames (is that correct for PAL?)  I then altered the Still Image duration from 150 to 125, although it is showing at 150 when I access General Preferences.  When I import a still image in, it says 5.00 sec under image in Project Assets but when added to the project all the images say duration 5.01 secs.  I have no idea what I've done wrong and why 5.01 secs seems to be the duration.
Please could anyone tell me how to reset the General Preferences back to default settings, if this can't be done, what should I have all the General Preference settings at for PAL?
Many thanks in advance for your help.

Same thing in Premiere Elements 10 and 12.
If you have a PAL project, when you open Edit Menu/Preferences/General, you will see defaults
Video Transition Default Duration = 30 frames
In the PAL project 25 frames/second, those 30 frames are equivalent to 1.20 seconds.
Audio Transition Default Duration = 1.00 seconds
In the PAL project 25 frames/second, 1.00 second is equivalent to 25 frames
(frames vs samples for audio is another story for another time)
Still Image Default Duration = 150 frames
In the PAL project 25 frames/second, so those 150 frames are equivalent to 6.00 seconds.
The above defaults will apply to all the stills that are imported AFTER the sets are made.
If you want to change the Still Image Default Duration for the project from 6.00 to 5.00 seconds, then BEFORE Still import you change
150 frames to 125 frames. That gives 5.00, not 5.01 seconds.
Examples
6.00 second duration = 150 frames
5.00 second duration = 125 frames
4.00 second duration = 100 frames
3.00 second duration = 75 frames
2.00 second duration = 50 frames
1.00 second duration = 25 frames
Again, these settings are done BEFORE and not after Still import.
If you are in the project with your Stills already on the Timeline with the Still Image Default Duration of 150 frames (6.00 seconds) as defined in preferences and you decide to change the duration of the Still from 6.00 seconds to 5.00 seconds, then you right click the still, select Time Stretch, and set the Time Stretch dialog to 5.00 seconds.
Example in Time Stretch dialog....from 00;00;06;00 to 00;00;05;00 (hours;minutes;seconds;frames).
This can be done for one Timeline Still or more than one Timeline Still at a time.
Please review and consider and then let us know if you are OK with the details.
Thank you.
