STM32Cube IDE debugger, What is difference in Details & Default value of expression

[TDesh.1]

As per screenshot, while debugging I am getting different values in Details & Default value of NDTR expression. What is the difference in these 2 fields? Thanks

DMA is not paused when the debugger is paused. So, readings at different points in time may yield different values.

Some peripherals can be configured to pause when the debugger pauses. See __HAL_DBGMCU_FREEZE_ macros.
