Design Studio Issue with HANA calculated Column

Hi BO Design Studio Experts,

I am facing an issue using Design Studio(DS) on HANA: In HANA, I have a calculated column with multiple if statement, and it worked perfectly in HANA. However, in design studio, it interprets the HANA calculated column differently: I have a calculated column CC_BLOCK in HANA as below:

if("CreditBlock"='Y', 'Credit Block', if("BillingBlock"='Y', 'Billing Block',if("DelvBlock"='Y', 'Delv Block','')))

In HANA, it worked perfectly, however, in DS, the 'Delv Block' does not showup, instead, it shows only a '#' .

I found out the issue is: some orders may have both billing and delv. blocks, however, when DS interprets the HANA calculated column, for a record with both blocks, it just goes to the first block and ignore the others, so it only shows 'Billing Block', but only # for the Delv Block.

we're using HANA SP8 and DS 1.4.

Any help or solution will be highly appreciated!
