Problems with ippiLUT

Hello,
I have a problem with ippiLUT. Following code:
Hello, following code:
 

int values[] = { 5, 6, 7, 8, 9, 10, 11, 12, 13, 14 };
int levels[] = { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 };
uint8_t data[] = { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 };
uint8_t outData[10];
IppiSize roiSize = { 10, 1 };
int specSize = 0;
int numLevels[1] = { 10 };

const int *valuesPtr[] = { values };
const int *levelsPtr[] = { levels };
ippiLUT_GetSize(IppiInterpolationType::ippNearest, ipp8u, ippC1, roiSize, numLevels, &specSize);
auto spec = (IppiLUT_Spec*)ippMalloc(specSize);
ippiLUT_Init_8u(IppiInterpolationType::ippNearest, ippC1, roiSize, valuesPtr, levelsPtr, numLevels, spec);
ippiLUT_8u_C1R(data, 10, outData, 10, roiSize, spec);
ippFree(spec);

I guess, outDatais wrong for last pixel, which has a value of 9 but should be 14. Do I use it wrongly or is this a bug?
I'm using IPP 2019.0.4.

Best regards Steffen
