Doesn't show values from scoreboard when using tellraw with other text

[Vanguard-Fx]

When using tellraw command:

• /tellraw @a [{"score":{"name":"test","objective":"test"}},{"text":" some text"}]
• Should be: 10 some text
• Real: some text

Using the same command without additional text:

• /tellraw @a [{"score":{"name":"test","objective":"test"}}]
• Should be: 10
• Real: 10
