Observations on the annual report, page-8

The previous poster is referring to where the deferred revenue is used in Note 18D, not on the balance sheet.

Note 18D is concerned with liquidity, whether the company can pay its bills as they fall due.
For a normal company, the cash has already been received for the deferred revenue and the company does not have to pay out cash to satisfy that liability in the future.

From Note 18D of the report:
"The objective of managing liquidity risk is to ensure, as far as possible, that the Group will
always have sufficient liquidity to meet its liabilities when they fall due. Working capital primarily comprises of cash. The Group has established the following processes for managing liquidity risk: regularly forecasting cash flows and monitoring actual cash flows against the forecasts; and monitoring the availability of equity capital and current market conditions."

Thus the original post is accurate and it seems you are attempting criticise it without first understanding it.
