TABLE --- BLOCK SIZE - HELP

Question

Hi,
Good day to all.
There are totally 4 tables(EMP, DEPT, STORE_INFO,WAREHOUSE_INFO) which has the range partition been applied.(Partition is on the date range for current date i.e. for every 1 day the partition will be automatically created)
There is a timer concept been applied such as the purge should automatically be done based on the days we pass.
But I can see the information in my table as “11 – Which indicates that the table is overloaded”.
For my surprise; for all the tables (NUM_ROWS and BLOCKS is NULL) except “EMP” table for which the NUM_ROWS IS NULL and BLOCKS size is 1,540,356.
1)     Will this be an issue during purge?
2)     Why NUM_ROWS is NULL and BLOCKS size is showing high.
Please help....

Thanks Hemant for your prompt reply.
Sorry and forgot to mention that this information is for our records "11 - Status which moves when table is overloaded".
Actually i was in an assumption that "because of the BLOCK SIZE" the table overloaded issue was getting raised.
Is the below code right?
When i am running it; it says the
Error
===
ORA-20000: TABLE "MOQ"."EMP" does not exist or insufficient privileges
