It is not “just your Obsidian”. The problem (if you call it that) is, that the Community Plugin “DataView” interprets the “=” of the “=>” as the beginning of an inline query, which is a kind of “show me all the notes, that have these contraints” request. It seems you are not using these inline query so you should be fine to change the “Inline Query Prefix” in the options for DataView to something like “==” instead of “=”.
