Filler immediately goes to places it shouldn't, is it me or is it the doctor?

When i get filler it immediately goes to places it shouldn't. For example my tear trough when the doctor tries to fill it, it just squirts to somewhere else. He did my cheeks and it went much further down then it should. On a visit i left the room then wanted to see him straight away again because i noticed it didn't look right. He said that sometimes when you apply filler it can spread out all over the place. Is that true? Should i see another doc? He is a certified dermatologist that i saw
