Sharepoint List : not saving the modification when updating two time the same row

Hello,

I'm using the modification window (in the right of the picture) without Power Apps. 

If a update an value into one row of the list, the correction is saved. But next if I close the modification window and open again to do another correction, the value is not saved. The only solution I founded is to refresh the browser. I tried with most commun browser and nothing seems to work proprely.

Is there any way to solve it or did I refresh my sharepoint everytime I do a modification

thanks for your help. Kr.
