Mixed up languages on different base map zoom levels

Blender and OS versions

Blender 3.6.5, Windows 11

Describe the bug

On different zoom levels I get different languages on a base map. On some levels even several different at once.

How to Reproduce

Add Base Map > Zoom...

Error message

There is no crash.

I've made little modification to buildURL with Polish (I've wanted it) language - url += "&language=pl":

` def buildUrl(self, laykey, col, row, zoom):
"""
Receive tiles coords in source tile matrix space and build request url
"""
url = self.urlTemplate
lay = self.layers[laykey]
tm = self.srcTms

	if self.service == 'TMS':
		url = url.replace("{LAY}", lay.urlKey)
		if not self.quadTree:
			url = url.replace("{X}", str(col))
			url = url.replace("{Y}", str(row))
			url = url.replace("{Z}", str(zoom))
			**url += "&language=pl"** 
		else:
			quadkey = self.getQuadKey(col, row, zoom)
			url = url.replace("{QUADKEY}", quadkey)
			**url += "&language=pl"** 

	if self.service == 'WMTS':
		url = self.urlTemplate['BASE_URL']

	return url`
