Increment bug

I think Increment action does not work well on Glide Pages. I use Google Spreadsheet as a databese and connect multiple projects on the same sheet. Last time, Increment worked even I have multiple projects but it doesn’t recently.

On Project 1, when I increment number by 1 twice, the data will be 2. And after that, on Project 2, increment number by 1 twice. It should be 4 and last time it showed 4. But recently it showed 2. Has Glide changed how to process increment action? Cannot use same column over the multiple projects?

Can you reproduce that supposed bug in a video?
