Mermaid don't draw arrows in links. No background on link label

[GSoftwareDevelopment]

I used the mermaid extension to draw the diagram, however, even though I indicated in the code that the links between blocks should be terminated with an arrow, this one does not.
There is also no background for the link labels, causing them to overlap the link line.

Code:

flowchart TB
	A("START") --> A'[["getLayoutColorsData"]]
	A' --> B[["parseLayoutBefore"]]
	B --> C[/"for each line definition"/]
	C --> D[["buildLineSchema"]]
	D --> E[["parseLineBefore"]]
	E --> F[/"for each elements in line definition"/]
	F --> G[["parseElement"]]
	G --> H{"It is last element?"} -- No --> F
	H --> I[["parseLineAfter"]]
	I --> J{"It is last line?"} -- No --> C
	J --> K(END)
