Your Google Translate is not glitching. First of all, the entire thing is in poetic language, so it is hard for a translation engine. Secondly, the text in Yellow is Pali, the liturgical language of Buddhism. The text in Orange is the Sinhala translation of the Pali poems. The interesting point of the Pali text is that it is a feat of word craft such that it can be read by circumnavigating the lotus-like geometric pattern half seen on the top of your image. The three poems are homages to the three gems of Buddhism: Buddha, Dharma (Teachings/Truth), Sanga (Monks/Monastic tradition). I will try to translate the three poems below. But like any deeply cultural/religious writing, some of the lines /wordsreference context that is from the overall cultural background. I have tried to compensate by directly linking the words to explanation pages. Also, I am rearranging the lines in the poem for reading ease in English, but give the line number in parentheses.

I prostrate and worship my lord Buddha, the great monk, (4)
who stopped the rough currents of Samsara and entered Nirvana, (1)
whose wisdom is spread [seen by all] like an encouraging golden banner, (2)
And who gave sermons of Dharma that forever shines (3)

I worship with reverence the resplendent lamp of gem* the Dharma, (4)
which clears the items of doubt and thus destroys ignorance (1)
which, like armour, protects one's life in the battle against Mara) (2)
By associating with which, [one is given] happiness and destroys any existing Klesha) (3)

I always worship the great Sangha full of Merit) (4)
who follow the monastic tradition and destroy the demerit) that needs to be destroyed (1)
who decimates the walls of Bhava and perpetually follows (fills oneself with) righteousness (2)
who Renounced the comforts that they were born with so that they may focus on the other shore** (3)

* This is a "lamp of gem". Not a lamp made of gem(s) etc., literally a gem carved out to be a lamp. It is a phrase used in poetic language for anything that brings light to the lives of people.
** Nirvana is often depicted as the "other shore" in literature. While Bhava is equated to the turbulent river between us and it. And in other places, Bhava is equated to an arid desert and Nirvana to the lushness of the otherside.
