On both desktop & mobile an extra blank line is being added to the frontmatter because of this \n. I removed it in my local copy but wasn't sure if it should be part of this PR.

const frontmatterPosition = this.app.metadataCache.getFileCache(file).frontmatterPosition;
const fileContents = await this.app.vault.read(file);

const deleteFrom = frontmatterPosition.start.offset;

This isn't ideal because if anything's null/undefined then destructuring will throw an exception, but that would happen even before this change.

FYI: v1.4.0 of the obsidian types includes both of these properties now obsidianmd/obsidian-api@90517f4

const filecontent = await this.app.vault.cachedRead(file);

const yamlContent: string = filecontent.split("\n").slice(start.line, end.line).join("\n");
