Thanks for contacting Syncfusion support.
We have analyzed your provided code example and we suspect that you have rendered the Grid controls initially in two different accordion control’s item that the waiting popup positioned correctly for the first Grid due to initially it is in visible state. The cause of the issue is that the second Grid initially in hidden state. So, that the waitingPopup show in left position is due to width is setting as 0px when the Grid is initially in hidden state. . To overcome from this we suggest you to render the grid when accordion item is active using activate event. Refer the documentation link.
