BLE Examples - Custom Profile Characteristic Descriptions do not display on Android devices

Using DA1458x SDK 5.0.4

When compiling and running the BLE Examples in the SDK directory \DA1458x_SDK\5.0.4\projects\target_apps\ble_examples
I have not been able to display the Characteristic User Description strings for any of the custom entries using any Android device running BLE Scanner, et al.
However when I run these BLE examples on an iOS platform running Lightblue Explorer, ALL of these fields are displayed properly.

The strings are located in the user_custs1_def.h file:
for example:
#定义CUST1_CONTROL_POINT_USER_DESC”Poi的控制nt"
#define CUST1_LED_STATE_USER_DESC "LED State"

On the Android device, An R button appears on the right hand of the screen for each field, but the R button doesn't do anything.

I have run this using the SDK ble_app_peripheral, ble_app_all_in_one, and several other examples... all with the same results.

Any ideas?

thanks
