collapsed element leaving wierd gap in mobile version only

Hi everyone, I’ve been trying to find the solution by searching, but wasn’t able to. My site is OK at desktop version, but there is this problem in mobile. See bellow in the print screens. I already tried everything, there is nothing behind the collapsed object that could be generating the gap, and in Desktop it works.

Since collapse is a dev mode feature I posted it here, hope its the right place.

Are those to buttons in a strip that is set up as collapsed on load?

If so they they should be greyed out in the Wix Editor and you simply need to move everything up on the Wix Mobile Editor to close the gap, basically the blue strip should be where it is when the strip element above it is collapsed.

See this page here for more info on how elements affect your page layout if collapsed for example.

I’m not sure if I understood. Yes, the strip is collapsed on load, and there are these two buttons already inside the said strip, one actually is inside a button in a repeater inside the strip. They are greyed out (?), or at least with that little strips that cover collapsed ellements, as you can see in the amplifyed image bellow (or is it litterally that they should be the “color grey”?). The blue strip bellow the colapsed ellement is already touching the limit of the collpased strip. If I put the blue strip (its another repeater acctually) occupying the same palce (but behind) as the collapsed ellement, when I activate the “uncollapse” trigger, the strip that uncollapse covers the blue repeater (what is not my intention), instead of sending it down.

i am trying the reading you indicated, but there are no gap bigger than 70 pixels, in fact there seems to be no gap at all between the items. (note how its not mantianing distance between item before the collapsed strip and my repeater, but “generating” another sized gap instead)

Sorry for the trouble, i’m really lost, and with a short deadline

Editing answer: I tried to hide the strip in the mobile, (using del) to see if there was something wrong behind it all, and as I used ctrl+Z to make it all get back, it started to acted as I wanted O.o. So its ok now. Thank you for helping me. ^^
