Can't see legend of created map in google maps on the map on iphone

Hello! I have an issue with my google maps on IPhone. I created a map and unfortunately from my phone i can't see map tags (legend) on the map. I can see only legend (list of places I want to see) and when i check them on the map - its clear, no marks. If this issue will not be fixed i will have difficulties with my trip as it will be hard to walk around some area without seeing where to go. Can someone help me to fix it?

Thank you in advance!
