Text included in blocks is not well scaled when changing unit

In a meter unit file, I have these items (one block and a 2.5m dimension). In the following image the block is edited.

I close the block and copy the 2 items and paste them in a minimeter unit file :


The cylinder and the 2.5 dimensions are right but not the text and the 1000mm dimension in the block.

In the current minimeter file, when editing the block, the 1000mm dimension is right but not the text “beton”.
In the following image, the 1000mm dimension is selected.


In the following image, zoomed out, the text “beton” is selected:

If you stop editing the block, the 1000mm dimension is wrong again.
