PCA9745B Step time control registers, possible error in datasheet?

Hello!

Please explain to me what was meant and whether there is an error here:

source: https://www.nxp.com/docs/en/data-sheet/PCA9745B.pdf 

page 15, table 13, STEP_TIME_GRP0 to STEP_TIME_GRP3, step time control registers

It follows from the table that for the STEP_TIME_GRP0 register, the seventh bit is reserved (!) And thus we cannot control the step time (rise / fall) for a group of zero?

Perhaps this is a document layout error?

Maybe there should be such a distribution of bits for the registers indicated in Table 13:

0x29 STEP_TIME_GRP0 bit 7
0x2d STEP_TIME_GRP1 bit 7
0x31 STEP_TIME_GRP2 bit 6
0x35 STEP_TIME_GRP3 bit 6

PCA9745B‌

How really should be?

respectfully
Vladimir
