Hi
I don't think there is anything wrong with your upload. The fault is in the way VP actions the STOP/START with the Space key.
Your upload contained two files....
2018-01-05 18-05-38.zip and Tuna MRE2.MOV
The zip opened as shown here:

The first thing to note is that you have uploaded Tuna MRE2.MOV twice; once in the zip and one as a separate file. (Not a problem)
Your Ep 1 Lemon Tuna Ingredients, Cooking.vpj fil opened correctly into VP, and loaded correctly to the timeline.
Not all of the video clips loaded to the timeline. Only Tuna Cooking 6MOV; Tuna Cooking 7MOV and Tuna Cooking 8MOV were being used The others remained in the clip bin. (Again, not a problem)
Of the two audio files loaded only All Up in my Jam.mp3 was used. Tuna Cooking 8.MOV was not used. (Seemed to be radio recording).....So you had some redundant files in your project. (Once more not a problem)
Having said all that the timeline played normally when using the STOP/START button under the Sequence Preview screen.It stopped and and continued using repeated presses of the centre button. This is normal.
However, using the Space bar to Stop/Start in the same way the playback was as you reported - The cursor line skipped.
Was this due to you holding down the Space key??
Do you have the key auto repeat too short.
Quick on/off presses seemed to work OK. Keeping the key depressed made the cursor line jump to the end or start of the timeline.
Note that the action of using Space is not the same as using the sequence screen Stop/Start button as the latter only actions once it is released, Space actions when it is pressed.
NCH might be able to change this action??
