EMail Template via HTML - after saving just Text

Hi,

We're using Sugar Prof. Ver. 7.9.5

I try to create a Email Template with HTML Code.

So i put the HTML Code in the Editor and after the update the Template looks fine as it should.

But after Saving there is just some Text and when i open the Template the Test is there and also in the Editor the HTML Code is different.

Any Suggestions?
Maybe anything special before saving?

Best,

Lennart
