[MapProxy] Map shift between TMS and WMS

Hi,
I have a shift of my map in comparison to TMS between WMS layer.
I have a mapnik OpenStreetMap source and a wms relief source. If I use
the OpenStreetMap source as a tms and overlay the relief source as wms,
there's a vertical shift of the data so that it is not overlaying
correctly. If I use the OpenStreetMap source as wms and the relief as
wms, both are overlaying correctly. Now I wonder what may be the cause
of this behavior? Is this maybe due to the bounding box with which the
grid is configured?
83 grids:
...
95 cv:
96 srs: 'EPSG:4826'
97 res: [1222, 610.984, 305.492, 152.746, 76.373, 38.187,
19.093, 9.547, 4.773, 2.387, 1.193
98 bbox: [-26, 14, -22, 18]
99 bbox_srs: 'EPSG:4326'
I uploaded my config here [1] and a live example here [2]. Use the last
WMS server in the layer switcher for testing, the others aren't working
currently. If you zoom closer to an island you will notice the
difference in position much better.
Any tips are greatly appreciated
Frank
