SPI slave not reading the data in first run

Hi all, i got to know a bug/problem/issue in SPI communication. one of my colleague is working on designing controller(complete SDK), he has an issue, the issue is, whenever he writes the data from master it writes properly, but when trying to read the dta, he is not able to read it in one run, for second run data can be read, but for first run its taking some garbage value. if nay one has faced such issue? any suggestions for what might be the problem for this,? clock phase and clock polarity are same no change in that.
