Standby stop applying archivelogs

Question

Hello,
yesterday, for the purpose of purgering flashback logs (it occupied a lot of FRA space) in standby, I dropped one 'restore point' in the standby database, and 'rm -r' one flashback log (because not very sure, so only rm one flashback log).
this is what I did
cc:
To remove uncessary Flashback Logs, you need to do the following:
1) drop any Guaranteed Restore Points that you don’t need (e.g. drop restore point ===> done in standby
2) set the init parameter DB_FLASHBACK_RETENTION_TARGET adequately ===> done in standby
3) Log in as root and run the following statements:
ls -lrt …/flashback|tail -100 =====> only 'rm' one flashback log (in asm )
prepare delete statement for each file you want to remove
(e.g. rm -f)
then this morning, I found last Applied log is stuck in yesterday afternoon. the stanby database won't apply archivelogs.
SYS> alter database recover managed standby database using current logfile disconnect;
alter database recover managed standby database using current logfile disconnect
ERROR at line 1:
ORA-01153: an incompatible media recovery is active
Any idea to fix those problem?
thank you
