[ABANDONED] Strange error message in Segger Embedded studio

I try to build a project that was originally built with an older eclipse ide (eclipse neon)

I get this error code:

'BME680_NBCONV_SELU' undeclared (first use in this function); did you mean 'BME680_NBCONV_SEL'?

when I go to the line with the error i see this:

#define BME680_GAS_SENSOR_SELUINT16_C(BME680_GAS_MEAS_SEL | BME680_RUN_GAS_SEL | BME680_NBCONV_SEL)

there is nower an U after SEL ... what could I do?

I tried to delet a part of BME680_NBCONV_SEL and rewrite it or make a space between L and ) all of this don't solve the problem...

I use up to date version of segger (V4.52 64 bit)

thanks for any help

I replaced all the related h files with the same identical h files, and it works... very strange
