qgis - Print Composer exporting different image with Thunderforest base map

I prepared a map in the Print Composer of QGIS. The scale of the map is 1:150,000,000. I imported the Thunderforest Pioneer base layer. At the scale I used, country labels do not show when working on the map in Print Composer.

Note that I locked the layers and locked the layer style.

Here's a screen shot of what I see in the PDF export:

Here's a PDF of what I see when I right click on the base layer and select properties:
