EE invite e-APR personal history

[royalstellar]

I am working on my e-APR

I have completed every section aside from the last "personal history" section.

this section is divided into

personal activities
travel history
statutory questions

I have completed all the required sections but would not show as complete.

only thing that i can think of "gaps in time" under personal activities. Could this be? what else could be the reason?
If so,during the months (or years) i didnt work or study, should i have to fill out? and say what?

please kindly help. My health is declining as well.
