Thanks a lot for your help. for the Red rem, just searched my base, it shows as below:
You can find there is a unnamed rem has power up flag.
And I found more untiled page with power up rems. sadly.
This mainly caused by I just use remnote in my MBP?
I could force delete them and ignore the errors, but after I use remnote in other devices, the issue will be popped up again
After force deleted the Untitled rems, i searched Red rem again. it shows below:
That’s string there are 2 Colors? Any suggestions?
Waiting for your kindly help. Thanks again.
