Zoom H5 "A/B Repeat" and "Repeat One" loops are not seamless

I have an audio loop which is seamless - meaning you cannot say where the loops starts and ends. When I use “A/B Repeat” or “Repeat One” to loop this audio, H5 seems to add some half second silence after loop ends (or before it begins) which effectively breaks possiblity to have a nice, seamless loop.

Have you experienced it? Is there any workaround for it?
