Same behavior with my 520's. Of course this is something the software is doing, but it's possible it was a conscious decision by the programmers, or a mistake too. Non-Intel SSDs have their raw SMART data displayed in hexadecimal too.
A few of the SMART values were never displayed in a format that made sense to the the user, like power on hours count. The power cycle and unsafe shutdown counts are simple to translate to decimal and seem to be reasonable values, in the OP they are 274 and 269 respectively in decimal.
Raw data in most cases must be translated into a user friendly value, as I imagine the total LBAs read and written values are. If so, they really aren't raw data values, are they? Not that it matters to me, SMART data reporting has always been a non-standardized mess. 0x0 still means zero in decimal, and the Windows calculator in Programmer mode can easily change hex values to decimal.
