I have had this happen several times, but now I think I know what is going on.
When you use a Glide Table, deleting rows is a bit hit and miss (it seems). So you are not sure if the row is deleted or not. It is easy to press delete more than once.
Then you go back into the UX designer…
And I find that, in one of my tabs (not sure the logic which one), the design components (starting from the top) have been deleted.
Bleargh.
How did you put that background?
<div style="position: fixed; opacity: 1.0;
top:0px; left: 0%; z-index:-1;" target="_blank">
<img src="https://storage.googleapis.com/glide-prod.appspot.com/uploads-v2/Nlrw4jqEKYY2NEab88yM/pub/8B8ckhXusKewiBp9YIMq.jpg" style="height: 52em; ">
<pre><div><style>
[data-test="glide-app-bar"] :nth-child(1) {
backdrop-filter: blur(0px);
background: transparent;
-webkit-backdrop-filter: blur(0px);
}
#app-root div[opacity='1'] {
color: transparent;
}
CSS - make a rich text component and paste it in. Then change the URL for the image.
Thanksss
are you using “Select Mode”?
I don’t know what you mean… !
This mode of selection.
Personally I avoid using it, because from the start there was a bug (I don’t know if it still exists), if you are in ‘Select Mode’ and you use the ‘Delete’ key in a table or whatever, the components were deleted at the same time.
Ah - now I understand. Yes, I use ‘Select Mode’ almost all the time.
I guess I will just need to be very very careful about deleting things from a Glide Table.
In fact I rearchitected my app to now create and delete rows anymore. Instead I have a table for ‘TestFlow’ that is created when a user create an account, and I keep writing to that row - and clearing it once the process is done.
I use the other mode and when i want to “select” something i click and maintain ctrl or cmd and click the component. It’s a way to use play mode but select some components when needed.
Cool - I learned a new thing! Thanks 
I warned you about this in my video
