E810_8.97.2.1_unknown column security with blank object name created

Hi, not sure what has caused this happen. My user tried to create some column security in order to revise the change permission to Y..

But in the midst of doing it, Eg..

Before saving the security in P00950

.DMHQPROD

P4310

After saving the security

            

.DMHQPROD	blank	ICPNPR002	2	Column Security	DescriptionLine1		DSC1	Y	N	Y
.DMHQPROD	blank	ICP0008	2	Column Security	AmtPricePerUnit2		UPRC	N	N	N

after saving, both of the above new line could not be removed in P00950..
