This is by design, you have the option to 'Flag out-of-date symbols' set in the DC options. If this is set it warns you when the symbols have been changed in the library since you placed them in the schematic. You can set this option to No under Tools - Options - Settings Tab.
It's so kind of you to help me solve this issue, it works, thank you！
Also I can make the text vanished by replace this symbol instead of latest version
But I have another question: After I set it to NO, will it cause other issue in the following works like forward annotate to PCB, does it cause any problem to layout? I want to know the risk after I choose don't flag the out of date symbols
Besides, I have another question, please see below picture
When I verified the schematic, it's said the page stamps(is it called page stamps?) are missing instance name, I deleted the page and inserted a same one, but this error still exists, so could you have any way to fix it?
I'm looking forward to your early reply, thank you!
