Yes, the results for APAC are omitted. They will always be omitted in any fixed effects model you do. There is no getting around this, and it is not a problem. Don't worry about it.
What you should have from the code in #8 is regression results for APAC#$xlist interaction terms, and the corresponding marginal effects of the xlist variables at each level of APAC. This tells you how the APAC variable modifies the effects of the xlist variable: that is the only information about APAC you can get from a fixed effects model.
