I'm facing this issue with certain components in my board. After manually editing almost 60% of my components by renaming part prefixes, for few of the components when I try to change their prefix names, two types of behavior I have observed. 1\. After saving new name in schematic\, on clicking "Update PCB"\, the old component is deleted and a new component is placed in its place arriving very far on the layout section with no prefix visible even when prefix visibility is set to 'Yes'\. \[U34 changed to U4 in schematic \- Image for this is given below\] 2\. Some components although show changes in import changes screen but they do not change in layout\. I have built 2-3 boards earlier using easyEDA never faced this issue. Any help is greatly appreciated.
