Elusive Time Stretching results that are good

I have a project that uses 4 loops that are 96 BPM (acoustic guitar)

I want to increase by 5% ->100.8 BPM

I select groove clip, stretch to tempo
Also tried looping
Turn off follow pitch

It sounds phasey and unacceptable

I bounce clip

Still phasey

I try audio -> stretch to length

Sounds Great.. But the resulting clip is in sync for 4 BARS then goes out of sync
Used Radius Mix, Advanced and MPEX

Does anyone have any recommendations on how to get acceptable time stretches? This is driving me mad!!
