Issue updating dataset with all pages

Hello,

I have added the same dataset to both of my pages.
On the first page I update the dataset based on the user input:

// The dataset already start with the elements and we only update them
let count = $w( “#memberDataset” ).getTotalCount();
$w( “#memberDataset” ).getItems( 0 , count)
.then( (result) => {
let items = result.items;
if ($w( ‘#codingSwitch’ ).checked === true ) {
items[ 0 ].passionParam = $w( ‘#codingPassionRank’ ).selectedIndex + 1 ;
items[ 0 ].expertiseParam = $w( ‘#codingExpertiseRank’ ).selectedIndex + 1 ;
} else {
items[ 0 ].passionParam = 0 ;
items[ 0 ].expertiseParam = 0 ;
}
})

// Saving the changes
$w( “#memberDataset” ).save()
.then( (item) => {
} )
. catch ( (err) => {
let errMsg = err;
} );

After moving to the second page, when I try to go over the dataset, it is gone, not even the initial parameters that were stored there:

let count = $w( “#memberDataset” ).getTotalCount();
$w( “#memberDataset” ).getItems( 0 , count)
.then( (result) => {
let items = result.items;
console.log(result);
if (items.length > 0 && items[ 0 ].passionParam === 0 && items[ 0 ].expertiseParam === 0 ) {
$w( “#codingIncomeptence” ).show();
}
})

However, if I go directly to the second page the stored parameters can be found.
So I guess somehow my update deleted all of it.

Thank you for any kind of help
