0PROG_POS_TEXT uses ATTR customer exit!

This is a strange one!

I created an enhancement for 0PROG_POS_TEXT in CMOD, customer exit EXIT_SAPLRSAP_003 (which is the customer exit for texts?), but when I debug 0PROG_POS_TEXT in RSA3 it calls up EXIT_SAPLRSAP_002 (which is for attributes)!

An idea why and how to fix it?
